# Force Experienced by Charges between Parallel Plates

• Kratos321
In summary, the force experienced by a charge at any point between two charged parallel plates is proportional to the magnitude of the charge and the electric field, and its direction depends on the sign of the charge and the direction of the field. This is true when the dimensions of the plates are large compared to the distance between them and the electric field is uniform and constant.

Hello,

Is the force experienced by a charge at any point between two charged parallel plates the same?

Just a preliminary step to my homework question,
Let's say I have two parallel charged plates. (positive on top and negative on bottom with field lines going downwards.).

Would all positive and negative charges experience the same force at any point between the plates?

thanks in advance.
cheers.

When the dimensions of the charged plates are large compared to the distance between the plates then the electric field E that exists between the plates is essentially uniform and of constant value.

The force experienced by some charge q between the plates is then given by q*E. So the magnitude of the force will be proportional to the magnitude of the charge and magnitude of the field, and the direction of the force depends upon the sign of the charge and the direction of the field.

## What is the force experienced by charges between parallel plates?

The force experienced by charges between parallel plates is known as the electric force or Coulomb force. It is a fundamental force of nature that describes the attraction or repulsion between two electrically charged objects.

## What is the equation for calculating the force experienced by charges between parallel plates?

The equation for calculating the force experienced by charges between parallel plates is F = Q * E, where F is the force in Newtons, Q is the charge in Coulombs, and E is the electric field strength in Newtons per Coulomb.

## How is the direction of the force determined?

The direction of the force experienced by charges between parallel plates is determined by the direction of the electric field. If the charges are of the same sign, the force will be repulsive and if they are of opposite signs, the force will be attractive.

## What factors affect the force experienced by charges between parallel plates?

The force experienced by charges between parallel plates is affected by the magnitude of the charges, the distance between the plates, and the strength of the electric field between the plates.

## How does the force experienced by charges between parallel plates change as the distance between the plates increases or decreases?

As the distance between the parallel plates increases, the force experienced by the charges decreases. This is because the electric field strength decreases with distance, resulting in a weaker force. Conversely, as the distance between the plates decreases, the force experienced by the charges increases.
