Electric Dipole

A dipole of dipole moment $\vec{p}$ is placed in uniform electric field $\vec{E}$ then torque acting on it is given by

Show answer and solution

Answer: (b)

Torque on a dipole: $\vec{\tau} = \vec{p} \times \vec{E}$ , magnitude $pE\sin\theta$ .
So the answer is (b) $\vec{\tau} = \vec{p} \times \vec{E}$ .
