An electric dipole (dipole moment p) is placed at a radial distance r >> a (where a is dipole length) from a infinite line of charge having linear charge density +λ. Dipole moment vector is aligned along radial vector r force experienced by dipole is :-

Options

• Option A

  $\frac{\lambda p}{2\pi\epsilon_{\omicron}r^2}$, attractive

• Option B

  $\frac{\lambda p}{2\pi\epsilon_{\omicron}r^3}$, attractive

• Option C

  $\frac{\lambda p}{2\pi\epsilon_{\omicron}r^2}$, repulsive

• Option D

  $\frac{\lambda p}{2\pi\epsilon_{\omicron}r^3}$, repulsive
