# For what position of an electric dipole in a uniform electric field is potential energy is maximum?

Contents

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.

## For what position of an electric dipole in uniform electric field potential energy is maximum or minimum?

Potential energy of an electric dipole is maximum when it makes 180 degree with electric field and minimum when angle between them is zero degree .

## 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.

## At what position is the electric dipole in 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. So, the correct answer is “Option A”.

## In which orientation potential energy of an electric dipole is zero in a uniform electric field?

From the above equation, we can see that the potential energy of dipole placed in an external field is zero when the angle Ɵ is equal to 90° or when the dipole makes an angle of 90°.

## For what orientation of electric dipole in uniform electric field is potential energy of dipole is greatest and least?

The potential energy is lowest when the dipole is aligned with E and highest if it is anti-aligned. If the field is not uniform, then the magnitude of the electric force acting on the positive charge can be different from that acting on the negative charge, and there can be a net force acting on the dipole.

## When an electric dipole is placed in a uniform electric field then at what angle?

An electric dipole of length 2 cm, when placed with its axis making an angle of 60o with a uniform electric field, experiences a torque of 83 ​ Nm.

## When dipole placed in electric field which position dipole has maximum potential energy?

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

## When an electric dipole is placed in a uniform electric field it experiences?

When an electric dipole is placed in a uniform electric field, it experiences a torque but no force. 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.

## What is potential energy of a dipole?

Potential energy of a dipole in an external fieldElectric 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 …

## What is the direction of electric dipole moment?

The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge. Dipole moments tend to point along the direction of the surrounding electric field.

## At what position is the electric dipole in uniform electric field in its I most stable position and II unstable equilibrium?

A dipole placed in a uniform electric filed is in Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when is parallel to. Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when is anti-parallel to.

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

When an electric dipole is placed in a uniform electric field, it experiences. An electric dipole placed in uniform electric field experiences a torque which align the dipole parallel to the direction of the electric field with zero net force.

## At which angle will the dipole be in a uniform E so that it is in dynamic equilibrium?

∴ PE is high in the case of θ = 180, the equilibrium will be unstable and when θ = 0 then PE is low, so the equilibrium is stable. The dipole is in constant equilibrium if θ = 0.

## When a dipole is in the uniform electric field the system has the least potential energy when the dipole moment vector and electric field vector are at?

The minimum potential energy of the dipole does not mean the potential energy to be zero. The potential energy of the dipole is minimum when the dipole is parallel to the external electric field.

## What orientation of the dipole has the least electric potential energy?

The dipole has its least potential energy when it is in equilibrium orientation, which is when its momentum is lined up with Electric field (then τ = 0) It has greater potential energy in all other orientations.
