MCQ (Single Correct Answer)

-1

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

$$\overrightarrow \tau = \overrightarrow p .\overrightarrow E $$

$$\overrightarrow \tau = \overrightarrow p \times \overrightarrow E $$

$$\overrightarrow \tau = \overrightarrow p + \overrightarrow E $$

$$\overrightarrow \tau = \overrightarrow p - \overrightarrow E $$
