A dipole of dipole moment 'p' is placed in nonuniform electric field along x-axis. Electric field is increasing at the rate of $1V{m}^{-1}$ then the force on dipole is

Given data: A dipole whose dipole moment can be presented by ' $p$ ' which is present in a non-uniform electric field along $x$-axis.

Concept used:

Detailed solution: electric dipole

The negative gradient of potential energy is described as force. $F=\frac{-dU}{dx}$

An electric dipole has potential energy of $U=-\overrightarrow{p}·\overrightarrow{E}$

Thus , the force appears as, $F=p\frac{dE}{dx}=p$
