Question

The torque acting on a dipole of moment $\overrightarrow{p}$ in an electric field $\overrightarrow{E}$ is .

• A. $\overrightarrow{p}.\overrightarrow{E}$
• B. $\overrightarrow{p}X\overrightarrow{E}$
• C. $Zero$
• D. $\overrightarrow{E}X\overrightarrow{p}$

Answer 1

The correct option is B $\overrightarrow{p}X\overrightarrow{E}$

Torque is given by $\overrightarrow{p}\times \overrightarrow{E}$.
