Q. An electric dipole of moment $overrightarrow {p}$ is placed in a uniform electric field $overrightarrow {E}$. Then (i) the torque on the dipole is $p times E$ (ii) the potential energy of the system is $overrightarrow{p}$.$overrightarrow{E}$ (iii) the resultant force on the dipole is zero.

In This post you will get answer of Q.
An electric dipole of moment $overrightarrow {p}$ is placed in a uniform electric field $overrightarrow {E}$. Then
(i) the torque on the dipole is $p times E$
(ii) the potential energy of the system is $overrightarrow{p}$.$overrightarrow{E}$
(iii) the resultant force on the dipole is zero.

Solution:

The torque acting on a dipole is given by $tau$ = p $times$ E, the potential energy of the dipoie is given by $U$ = – p. E and the resuitant force on the dipole is zero.
