The magnitude of electric field intensity at point B (2, 0, 0) due to a dipole of dipole moment,$\overrightarrow{\mathrm{p}}=\hat{\mathrm{i}}+\sqrt{3}\hat{\mathrm{j}}$ kept at origin is (assume that the point B is at large distance from the dipole and $\mathrm{k}=\frac{1}{4{\mathrm{\pi \epsilon }}_0}$)

• A

  $\frac{\sqrt{13}\mathrm{ik}}{8}$

• B

  $\frac{\sqrt{13}\mathrm{k}}{4}$

• C

  $\frac{\sqrt{7}\mathrm{k}}{8}$

• D

  $\frac{\sqrt{7}\mathrm{k}}{4}$
