Question

For what position of an electric dipole in a uniform electric field it's torque is (1) maximum(2) minimum??

Answer 1

Maximum is the answer

Answer 2

1) when the dipole is perpendicular to the uniform electric field the torque is maximum as sin90 is 1...

2) When the dipole is paced along the direction of the electric field then the torque is minimum as sin0 is 0....
