# Best answer: Does a dipole experience a force when placed in the non uniform electric field?

Contents

An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force.

## What happens when a dipole is placed in a 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.

## What will happen if electric field is not uniform?

Hence, an electric dipole placed in a non-uniform electric field experiences both a torque and a net force.

## What happens when an electric dipole is held in a non uniform electric field what will be the force and the torque when the dipole is held parallel or anti parallel to the electric field hence explain why does a comb run through dry hair attract pieces of paper?

So, when the electric field is not uniform then the net force will be non-zero and there will also be torque on the following system. If the dipole moment p is parallel or antiparallel to the external field E, the net torque is zero but there is a non-uniform force on the dipole E.

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

The dipole is represented by a vector from the negative charge towards the positive charge. If a dipole placed in nonuniform electric field, it will experience net force of attraction per meter towards electric field of large magnitude that is, F(net)=p(E2-E1).

## Is it possible a dipole is placed in uniform electric field but it doesn’t rotate?

When a dipole is placed in a uniform electric field and dipole vector direction is not parallel to field direction, each chargs of dipole experiences a force. Magnitude of the two forces are equal but in opposite direction. … Hence in uniform field, dipole experiences only torque.

## What is a non uniform electric field?

When magnitude and direction of electric intensity are not the same at all the points in the electric field, then it is called a non-uniform electric field.

## What would happen if the external field E is increasing?

If the external field E is increasing, the dipole moment P will have a net force acting towards the increasing field and when E is kept anti-parallel, the net dipole moment will have a force over the decreasing field. Explanation: When the electric field is not uniform, the net dipole moment will be zero.

## Why do the electric field lines never cross each other?

Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.

## Is it necessary for an electric dipole to experience a net force as well as a torque when it is placed in a non uniform electric field?

An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force.

## When an electric dipole is held at an angle in a non uniform electric 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.

## When an electric dipole is held at an angle in a uniform electric field?

1) the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.
