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”.

At what position is the electric dipole in uniform electric field in its most stable equilibrium position?

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.

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.

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?

Solution : P.E. is minimum, when θ=0∘, i.e., dipole is aligned along the field.

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.

At what angle potential energy of an electric dipole held in a uniform electric field is zero?

POTENTIAL ENERGY OF A DIPOLE IN A UNIFORM ELECTRIC FIELD

We have consider the value of θ from 90o to θ, since dipole axis is perpandicular to the field so potential energy is equivalent to zero.

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.

For what position of an electric dipole in a uniform electric field its potential energy is maximum unstable equilibrium angle between P and E *?

For unstable equilibrium, potential energy is maximum at equilibrium position. A dipole in a uniform electric field is in stable or unstable equilibrium according as the angle between the dipole and electric field is 0 or 180.

What orientation of an electric dipole in uniform electric field corresponds to its stable equilibrium?

-The dipole is in stable equilibrium when it is aligned parallel to the electric field (i.e. the angle between the dipole moment and the electric field is 0∘).

Which orientation in degree of an electric dipole in uniform electric field would correspond to stable equilibrium?

Which orientation of an electric dipole in a uniform electric field would correspond to stable equilibrium? When the direction of the electric dipole moment is aligning in the same direction as that of the Electric field the dipole is said to be in a stable equilibrium.
