## When two point charges are a distance d apart?

When two point charges are a distance d apart, the force between them is given by:

F=kQq/d^2

where k is the Coulomb's constant, Q and q are the charges of the two point charges, and d is the distance between them.

The force between two point charges is attractions if they have opposite charges, and repulsions if they have the same charges. The force is directly proportional to the magnitude of the charges, and inversely proportional to the square of the distance between them.

Coulomb's law is a law of physics describing the electrostatic interaction between electrically charged particles. It was first published by French physicist Charles-Augustin de Coulomb in 1785. The inverse-square law dictates that the force between two point charges is inversely proportional to the square of the distance between them. The magnitude of the force is also proportional to the product of the charges of the two point charges.

The force between two point charges is given by:

F=kQq/d^2

where k is Coulomb's constant, Q and q are the charges of the two point charges, and d is the distance between them.

Coulomb's law is valid for point charges only. It does not hold true for other objects, such as particles with extended surfaces, or for fluids.

The force between two point charges is attractive if they have opposite charges, and repulsive if they have the same charges. The force is directly proportional to the magnitude of the charges, and inversely proportional to the square of the distance between them.

The SI unit of charge is the coulomb (C). The SI unit of electric field strength is the volt per meter (V/m). The SI unit of electric potential difference is the volt (V).

The force between two point charges is given by:

F=kQq/d^2

where k is Coulomb's constant, Q and q are the charges of the two point charges, and d is the distance between them.

The value of Coulomb's constant is:

k=8.99 x 10^9 Nm^2/C^2

The force between two point charges is attractive if they have opposite charges, and repulsive if they have the same charges. The force is directly proportional to the magnitude

## What is the electric field between two point charges a distance d apart?

In the simplest terms, the electric field is the force that an electric charge exerts on another electric charge. The size of the force is proportional to the amount of charge on each object. The electric field between two point charges a distance d apart is given by the equation: E = k * (Q1 * Q2) / d2 where Q1 and Q2 are the charges on the objects, d is the distance between the objects, and k is a constant. The electric field is a vector quantity, meaning that it has both magnitude and direction. The direction of the electric field is the direction that the force would be exerted on a positive charge. The magnitude of the electric field is given by the equation: E = k * (Q1 * Q2) / d2 where Q1 and Q2 are the charges on the objects, d is the distance between the objects, and k is a constant. The electric field is created by electric charges, and it exists even when there are no charges present. The electric field is invisible, but it can be detected by its effects on other objects. The electric field can be used to exert a force on objects. The force exerted by the electric field on an object is called the electrostatic force. The electrostatic force is proportional to the charge on the object and the strength of the electric field. The electric field can also be used to create electric potential energy. Electric potential energy is the energy that an object has because of its position in an electric field. The electric potential energy is directly proportional to the charge on the object and the strength of the electric field.

## How does the force between two point charges a distance d apart change as the distance d changes?

The force between two point charges a distance d apart changes as the distance d changes in a few ways. The first way is that the force gets weaker as the distance d gets bigger. The second way is that the force changes from attractive to repulsive as the distance d gets smaller. The last way is that the force gets stronger as the distance d gets smaller.

The reason the force gets weaker as the distance d gets bigger is because the force is inversely proportional to the square of the distance. This means that the force gets weaker as the distance gets bigger because the force is proportional to 1 over d squared. The reason the force changes from attractive to repulsive as the distance d gets smaller is because the force between two charges is proportional to the product of the charges. This means that when the distance d gets smaller, the forces gets bigger and the force changes from attractive to repulsive. The reason the force gets stronger as the distance d gets smaller is because the force between two charges is inversely proportional to the square of the distance. This means that as the distance d gets smaller, the force gets stronger.

## How does the electric field between two point charges a distance d apart change as the distance d changes?

The electric field between two point charges a distance d apart can be calculated using Coulomb's Law. This states that the force between two point charges is equal to the product of their charges divided by the square of the distance between them. In terms of electric fields, this means that the force is equal to the product of the charges divided by the distance between them.

When the distance between the two charges is large, the force between them is small. As the distance between the charges decreases, the force between them increases. When the distance between the two charges is zero, the force between them is infinite.

The electric field is the force per unit charge. Therefore, as the distance between the two charges decreases, the electric field between them increases. When the distance between the two charges is zero, the electric field between them is infinite.

## How does the potential difference between two point charges a distance d apart change as the distance d changes?

In order to answer this question, one must first have a general understanding of what potential difference is. Potential difference, also known as voltage, is the difference in potential energy that exists between two points in an electric field. This potential energy difference is what causes charges to flow between these two points, creating an electric current. The potential difference between two point charges a distance d apart can be calculated using the equation V=kQ/d, where k is the electrostatic constant, Q is the charge of each point charge, and d is the distance between the two point charges.

As the distance d between the two point charges increases, the potential difference between them decreases. This is because the charges are further apart and there is less of a potential energy gradient between them. The potential difference will continue to decrease as the distance d increases until the point charges are so far apart that there is effectively no potential difference between them and no current will flow between them.

## What is the force between two point charges a distance d apart if one charge is doubled?

When two point charges are a distance d apart, the force between them is given by:

F = (k * q1 * q2) / d^2

where k is the Coulomb's constant, and q1 and q2 are the charges of the two point charges.

If we double one of the charges, the new force will be:

F' = (k * q1' * q2') / d^2

where q1' = 2 * q1 and q2' = q2.

Therefore, the new force will be:

F' = (k * 2 * q1 * q2) / d^2

which is equal to:

F' = 2 * (k * q1 * q2) / d^2

or:

F' = 2 * F

## What is the force between two point charges a distance d apart if both charges are doubled?

The force between two point charges a distance d apart if both charges are doubled can be calculated using the following equation:

F = k(q1q2)/d2

Where k is the Coulomb's constant, q1 and q2 are the charges of the two point charges, and d is the distance between them.

When the charges are doubled, the force will be increased by a factor of four. This is because the force is directly proportional to the charges. Therefore, if the charges are doubled, the force will also double.

## What is the electric field between two point charges a distance d apart if one charge is doubled?

The electric field between two point charges a distance d apart is given by:

E=k*((q1+q2)/d^2)

Where k is the Coulomb's constant, q1 and q2 are the charges, and d is the distance between the two charges.

If one of the charges is doubled, the electric field between the two charges will be:

E=k*((2q1+q2)/d^2)

The electric field is directly proportional to the charge, so doubling the charge of one of the point charges will double the electric field between the two point charges.
