The workdone in rotating an electric dipole of moment P in an electric field E through an angle `theta` from the direction of the field is

A

pE `(1 - cos theta)`

B

2pE

C

zero

D

pE cos `theta`

Text Solution

Verified by Experts

The correct Answer is:
A, C
W = pE `(cos theta_(0) - cos theta)" " [ theta_(0) = cos theta, cos theta = 1]`
W = pE `(1 - cos theta)`
