Question 779: Electrostatics & Capacitance

Question

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

Accepted Answer

When an electric dipole is placed in a uniform electrical field $$\overrightarrow E $$, the torque on the dipole is given by
$$\overrightarrow 	au   = \overrightarrow p  	imes \overrightarrow E $$

Answer

$$\overrightarrow 	au   = \overrightarrow p .\overrightarrow E $$

Answer

$$\overrightarrow 	au   = \overrightarrow p  	imes \overrightarrow E $$

Answer

$$\overrightarrow 	au   = \overrightarrow p  + \overrightarrow E $$

Answer

$$\overrightarrow 	au   = \overrightarrow p  - \overrightarrow E $$
