When an electric dipole P is placed in a uniform electric field such that its potential energy is zero?

Typically we choose the zero point of potential energy for a dipole to be such that the average energy is zero if the dipoles are randomly oriented. That means that when the dipole is aligned perpendicular to the field the potential energy is zero.

When electric dipole is placed in uniform electric field such that its potential energy is zero then?

When electric dipole is placed in uniform electric field such that its potential energy is zero, then. torque acting on dipole will be. जब विद्युत द्विध्रुव को समरूप विद्युत क्षेत्र में इस प्रकार रखा जाता है

When electric dipole is placed in uniform electric field such that its potential is zero then torque acting on dipole will be?

For the torque acting on the dipole, first remember that in uniform electric field the torque becomes zero when the dipole becomes aligned to the electric field direction because the forces acting on the two charges is same but in case of non uniform electric field by point charge as the force acting on the charges are …

When an electric dipole having moment P is placed in a uniform electric field it will experience?

When a dipole is placed in a uniform electric field it experiences a torque which aligns to the direction of the electric field with zero net force. The torque acting on the dipole is given as the cross product of dipole moment and the electric field.

When an electric dipole is placed in uniform electric field its potential energy is maximum when?

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

Is placed in a uniform electric field?

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.

When an electric dipole is held at an angle?

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.

At what position electric field is zero in case of electric dipole?

Remember that field of a dipole is obtained by superposing fields of it’s constituent charges. As long as these charges are separated, their resultant field is not zero. From above formula for field, if 1+3cos^2(theta)=0, then field is zero.

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

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.

What is the net force on a dipole in a 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.

Why the electric field inside a conductor is zero?

Due to a large number of electrons, the force of repulsion acting in between them is also very high. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

At which point does a hollow sphere of charge not produce an electric field?

Beyond 10cm.

Does a stationary charge produce electric field?

A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
