# Your question: What does an electric dipole experience when it is kept 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 does an electric dipole experience when it is kept in the non uniform electric field a only a force B only torque c force and torque both D Neither force nor torque?

When a dipole is placed in an electric field, the opposite charges on the dipole both experience a force due to the electric field. … Hence the dipole will experience both force and torque when placed in a non uniform electric field. Therefore, the correct answer is option (B).

## 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 does an electric dipole experience when it is kept?

Now, 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 the same direction for both the charges. Hence torque will not be zero. Option (C) is the correct answer.

## When an electric dipole is held at an angle in a non uniform electric field the net force F and torque on the dipole are?

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.

## What happens if the electric field is non uniform?

➡️Torque is non zero when dipole is placed in uniform as well as non uniform electric field but in non-uniform electric field, dipole will experience net force of attraction whereas in uniform magnetic field, it doesn’t.

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

In the first case, the electric field is increasing parallel to ‘p‘. Thus that means the electric field on the positive charge will be larger than that on negative charge. Hence positive charge will experience more force than negative charge. … Hence negative charge will experience more force than positive charge.

## What happens when a dipole is placed in a uniform electric field?

Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field is always zero.

## 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.

## How does an electric dipole behave in an electric field?

In the presence of a uniform external electric field, the dipole aligns with the electric field (the direction from the negative charge to the positive charge being the same as that of the electric field) due to electric forces that are equal in magnitude and opposite in direction acting on the charges, and the net …

## What will be the value of electric field at the Centre of the electric dipole?

Therefore, electrical field at point p is the question mark. Since the total distance between the charges is d and this point is the center of the dipole, therefore this distance will be equal to d over 2.
