Two short dipoles are placed on \( x \)-axis as shown. Various distances and dipole moments have been marked in the diagram. Electric field at point \( P \) is
(1) \( \frac{p \cos \theta}{\pi \varepsilon_{0} r^{3}} \hat{i} \)
(2) \( \frac{2 p \cos \theta}{\pi \varepsilon_{0} r^{3}} \hat{i} \)
(3) \( \frac{p \sin \theta}{\pi \varepsilon_{0} r^{3}} \hat{j} \)
(4) \( \frac{2 p \sin \theta}{\pi \varepsilon_{0} r^{3}} \hat{j} \)
