When the angle between the dipole moment and electric field is 180° then the potential energy of electric dipole is maximum.

## At what angle between and an electric dipole of moment placed in a uniform electric field has minimum potential energy?

The potential energy of the dipole is minimum, that is [ – pE] when [cos theta = 1]. Therefore, we can substitute [0^circ ] for [theta ]. The potential energy of the dipole is zero, when the angle between dipole moment [vec p] and electric field [vec E] is [dfrac{pi }{2}].

## What is the potential energy of a dipole in a uniform electric field?

Let us consider an electric dipole of the dipole moment →P in a uniform electric field →E with →P making an angle θ with →E. , since the dipole axis is perpendicular to the field so potential energy is equivalent to zero.

## For what position angle θ between E and P of an electric dipole in a uniform electric field its potential energy is I minimum and II maximum?

The potential energy is maximum when the dipole is aligned anti-parallel (θ = π) to the external electric field and minimum when the dipole is aligned parallel (θ = 0) to the external electric field.

## At what angle dipole feels maximum torque in uniform electric field?

τ = p E sinθ

The value of sine function is maximum at an angle of 90°, i.e., sin90° = 1, so the dipole experiences the maximum torque at an angle of 90° with the field, or we can say that the dipole experiences the maximum torque when it is held perpendicular to the electric field.

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

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. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.

## What is the angle of electric dipole moment?

Dipole moment and electric field are opposite to each other on equatorial line. Hence the angle between them is 180 degrees.

## When dipole placed in electric potential energy of dipole is?

Electric potential energy of an Electric dipole in dipole from zero energy position to the desired position (The zero enrgy position to be one when the dipole When an electric dipole of dipole moment p is on it such that P= P× E This torque tends to rotate the dipole let dW the small amount of work done.

## At what angle potential energy is zero?

Originally Answered: When an dipole is placed in a uniform electric field with a angle of 90° or π/2, its potential energy is 0.

## Which of the following is correct for the energy of a dipole in a uniform electric field *?

An electric dipole’s potential energy at any location in a homogeneous electric field is U = -pE cos θ.

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

Electric dipole in a uniform electric field

An electric dipole placed in a uniform electric field experiences a torque that aligns the dipole parallel to the direction of the electric field with zero net force.

## At what angle between dipole moment and electric field electric dipole remains in stable equilibrium?

The dipole is in constant equilibrium if θ = 0^{}. A dipole in stable equilibrium, when Electric filed and dipole moment are perpendicular to each other i.e. the angle between them is zero degrees and torque will be maximum.

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

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.
