# How the torque and net force affected when the same dipole is placed in non uniform electric field?

Contents

## What is the net force and net torque experiences by an electric dipole placed in a uniform electric field?

Answer: In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. Though the net force will always be zero, the torque will be in same direction for both the charges.

## Does the torque exerted on a dipole in a non uniform field depend on the orientation of the dipole with respect to the field?

Electric dipole will experience a torque when dipole vector is not parallel to electric field direction. The torque τ = p × E = pESinθ. when p and E are parallel then angle θ between the two vectors is zero, hence there will not be any torque.

## How does the torque acting on an electric dipole affect it when placed in a uniform electric field?

How does a torque affect the dipole in an electric field? The torque tends to align the dipole in the direction of the electric field.

## What is the direction of net force on electric dipole placed in non uniform electric field?

The direction of electric dipole moment is from negative to positive charge. Hence the resultant force will always be non-zero.

## When an electric dipole is placed in a uniform electric field with its dipole moment parallel to the field it will experience?

Explanation :- A dipole is placed in a uniform electric field with its axis parallel to the field , means angle between dipole moment and electric field is zero. Hence, it doesn’t experience torque. Hence, it experiences force .

## How does torque on the dipole in uniform field depends on its orientation?

Derivation of Torque on an Electric Dipole

Let it be placed in a uniform electric field of strength E such that the axis of the dipole forms an angle θ with the electric field. … Notice that the torque is in the clockwise direction (hence negative) in the above figure if the direction of Electric field is positive.

## What happens to the torque on a dipole if the field is non uniform?

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.

## What happens to torque if field is non uniform?

No torque and no net force. … Now, for a non-uniform electric field there will be a torque on the dipole but also a net force. Once the dipole comes parallel to the electric field vector a force will act on the dipole in the direction of increasing field.

## When the torque acting on electric dipole in uniform electric field becomes maximum?

When an electric dipole moment is kept in an electric field, force acts on both charges in a dipole. The force acting on the charges acts as a couple and the dipole experiences a torque. The torque is maximum when it makes [{{90}^{o}}] with the electric field, which is the most unstable position.

## How the torque and net force affected when the same dipole is placed in non uniform electric field?

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.

## When a dipole is placed in an electric field E the torque induced on it is given by?

The electric dipole moment p of two charges +q and −q separated by a distance l is a vector of magnitude p = ql with a direction from the negative to the positive charge. An electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E.
