A dipole is placed parallel to the electric field. If \( W \) is work done in rotating dipole by \( 60^{\circ} \), then the work done in rotating it by \( 180^{\circ} \) is (1) 2 W (2) 3 W (3) 4 W (4) \( \frac{W}{2} \)

Step 1
The work done \( W \) in rotating a dipole from an angle \(\theta_1\) to \(\theta_2\) in a uniform electric field \( E \) is given by: \[ W = pE (\cos \theta_1 - \cos \theta_2) \] where \( p \) is the dipole moment. Show more…
