When an electric dipole is placed in a uniform external electric field parallel to the field it will experience?

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. In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction.

What happens when an electric dipole is placed in a parallel electric field?

Explain the force acting on electric dipole when it is placed parallel or anti parallel to electric field. When →p is parallel to →E or antiparallel to →E . In either case, the net torque is zero, but there is a net force on the dipole if →E is not uniform.

When the axis of the electric dipole is parallel to a uniform electric field the torque acting on it is?

In case the electric dipole gets parallel or antiparallel to the electric field then the torque will be zero.

Is electric field is parallel or anti parallel to electric dipole moment?

The dipole is thus in a stable equilibrium when it is parallel to the electric field. not in equilibrium.

When electric dipole is placed in uniform electric field?

zero
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.

What will be the value of electric field at the Centre of electric dipole?

Answer: Twice the electric field.

When a dipole is in the uniform electric field?

Therefore, the net force on the dipole is zero. 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.

What is the electric field of a dipole?

The electric dipole moment associated with two equal charges of opposite polarity separated by a distance, d is defined as the vector quantity having a magnitude equal to the product of the charge and the distance between the charges and having a direction from the negative to the positive charge along the line between …

What is an electric dipole moment and its torque?

Electric dipole p and its torque τ in a uniform E field. An object with an electric dipole moment is subject to a torque τ when placed in an external electric field. The torque tends to align the dipole with the field.

What happens when a dipole is parallel to an electric field?

A dipole aligned parallel to an electric field has lower potential energy than a dipole making some angle with it. For a spatially uniform electric field E, the energy U and the torque

How is dipole moment induced in neutral atoms?

A dipole is induced in a neutral atom by an external electric field. The induced dipole moment is aligned with the external field. An important fact here is that, just as for a rotated polar molecule, the result is that the dipole moment ends up aligned parallel to the external electric field.

What is the relation between dipole potential and charge?

which relates the dipole potential to that of a point charge. A key point is that the potential of the dipole falls off faster with distance R than that of the point charge. The electric field of the dipole is the negative gradient of the potential, leading to: Thus,…
