Question

An electric dipole is free to move in a uniform electric field explain its motion when it is placed (i) parallel to the field (ii) perpendicular to the field. What is the work done in moving the dipole from orientation (i) to orientation (ii)

Answer 1

the movement of the electric dipole will be linear in case of parallel direction with the field and in case of perpendicular field direction there will be  no movement of the electric dipole

Explanation:

• as there will be parallel electrical dipole arrangement and a electric dipole is at rest then there will be  attraction on one end and the repulsion on the other end. As a result of this there will be movement of the electric dipole towards the direction of the magnetic field.
• however in case of perpendicular orientation there will be neutralization of the attraction on one end and repulsion on the other end and hence there will be no movement or there will be rotational movement

• the work done will be dependent on the value of the dipole and the electric field
