# Does an electric dipole always experience a torque when placed in a uniform electric field?

Contents

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.

## Does an electric dipole always experience a torque in electric field when is the torque on the electric dipole maximum and minimum?

Answer: If the dipole moment vector is not parallel to the direction of electric field then both the charges comprising the dipole experience a force of equal magnitude but in the opposite direction. Thus it experiences only torque.

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

When an electric dipole is placed in a uniform electric field, it experiences a torque but no force. … In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction. The net force acting on a dipole placed in a uniform electric field is zero.

## What is the torque on a dipole in uniform electric field?

τ = (q E sinθ) d = q d E sinθ

Since ‘qd’ is the magnitude of dipole moment (p), and the direction of dipole moment is from positive to negative charge; torque is the cross product of dipole moment and electric field.

## When an electric dipole does placed in a non uniform electric field experiences a zero torque but non zero force?

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.

## Does a dipole experiences a force when placed in the non uniform electric field?

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.

## 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.

## How does a torque affect the dipole in an 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. The electrostatic force on a small sphere of charge 0.4 μC due to another small sphere of charge –0.8 μc in air is 0.2 N.

## What does an electric dipole experience?

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.

## How must an electric dipole be placed in a uniform electric field so that it experiences maximum torque show diagrammatically What is the magnitude of this torque?

i) When torque acting is maximum, dipole should be placed perpendicular to the electric field. ii) When torque acting is zero, dipole is placed parallel to the magnetic field.

## 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.

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

When electric dipole is placed perpendicular to the direction of electric field, then torque acting on it will be maximum.

## For what orientation does an electric dipole experiences a zero torque?

When dipole moment ‘p’ is parallel or antiparallel to electric field ‘E’ , the net torque is zero, but there is a force on the dipole E which is not uniform.

## When an electric dipole is placed in a nonuniform electric field the net force on the dipole is zero?

Answer. Answer: 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.

## Will an electric dipole have translational motion when placed in a non uniform electric field?

When a dipole is placed in a non uniform electric field it will experience both net force and torque . Thus , it willexecute both rotatory and translatory motion .
