Two mutually perpendicular wire carry charge densities \( \lambda_{1} \) and \( \lambda_{2} \). The electric lines of force makes angle \( \alpha \) with second wire, then \( \lambda_{1} / \lambda_{2} \) is
(1) \( \tan ^{2} \alpha \)
(2) \( \cot ^{2} \alpha \)
(3) \( \sin ^{2} \alpha \)
(4) \( \cos ^{2} \alpha \)
