Question

an electric diapole is place in a uniform electric field at the position of maximum torque, it is rotate and find the angle between electric field and diapole moment when torque is equal to half of the maximum torque​

Answer 1

Answer:

When an electric dipole moment is kept in an electric field, force acts on both charges in a dipole. The force acting on the charges acts as a couple and the dipole experiences a torque. The torque is maximum when it makes 90o with the electric field, which is the most unstable position.
