An electric dipole (dipole moment

\mathrm{p}

) is placed at a radial distance

\mathrm{r} \gg \mathrm{a}

(where

\mathrm{a}

is dipole length) from a infinite line of charge having linear charge density

+{\lambda}

. Dipole moment vector is aligned along radial vector

\overrightarrow{\mathrm{r}}

force experienced by dipole is:

View answer and explanation

Correct option: A

\frac{\lambda \mathrm{p}}{2 \pi \varepsilon_0 \mathrm{r}^2}

, attractive

Option A (

\frac{\lambda \mathrm{p}}{2 \pi \varepsilon_0 \mathrm{r}^2}

, attractive) is correct because the force on a dipole in an electric field gradient is proportional to the gradient and the dipole moment, and the force is attractive.
