Two short dipoles $\mathrm{pk} \& \frac{\mathrm{p}}{2} \hat{\mathrm{k}}$ are located at $(0,0,0) \&(1 \mathrm{~m}, 0,2 \mathrm{~m})$ respectively. The resultant electric field due to the two dipoles at the point $(1 \mathrm{~m}, 0,0)$ is :

(A) $\frac{9 p}{32 \pi \epsilon_{0}}$

(B) $\frac{-7 p}{32 \pi e_{0}}$

(C) $\frac{7 p}{32 \pi \epsilon_{0}}$

(D) none of these
