## For what orientation of the electric dipole in an uniform electric field is the Torque I maximum and II minimum?

Case 1: When Ɵ is 900 then Torque is maximum and is equal to pE which means the dipole moment should be perpendicular to the direction of the uniform electric field E. Case 2: When Ɵ is 00, then Torque is minimum.

## At what angle is the Torque on a dipole in a uniform electric field half its maximum value?

It is equal to pE/2 as sin 30 is half which means the dipole moment should be at an angle 30 to the direction of the uniform electric field E.

## For which orientation of the dipole the Torque acting on it becomes maximum?

Torque is maximum when dipole is held perpendicular to the field.

## When the electric dipole is placed in uniform electric field the Torque on dipole is?

Hence, the torque acting on the dipole is 0.

## When an electric dipole is placed in a uniform?

The net force acting on a dipole placed in a uniform electric field is zero. The forces on the two charges constituting the dipole are equal and opposite. Hence, the net force is zero.

## In which orientation a dipole placed in a uniform electric field is in unstable equilibrium?

-The dipole is in unstable equilibrium when it is oriented anti-parallel to the electric field (i.e. the angle between the dipole moment and the electric field is 180∘).

## 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 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.

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

Maximum torque acts on a dipole when the angle between P and E is maximum i.e. θ=90∘and its minimum when θ=0∘ in a uniform electric field.

## What is the orientation of an electric dipole?

The dipole is in stable equilibrium when electric dipole is in the direction of electric field vector and is parallel →P∣∣→E.

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

An electric dipole is placed in a uniform electric field E with its dipole moment p parallel to the field. Find (i) the work done in turning the dipole till its dipole moment points in the direction opposite to E. (ii) the orientation of the dipole for which the torque acting on it becomes maximum.

## 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.
