Problem

A charged particle q1q_1 is at position (2,−1,3)(2, -1, 3). The electrostatic force on another charged particle q2q_2 at (0,0,0)(0, 0, 0) is: (a) q1q256πϵ0(2i^−j^+3k^)\frac{q_1 q_2}{56\pi\epsilon_0} (2\hat{i} - \hat{j} + 3\hat{k}) (b) q1q25614πϵ0(2i^−j^+3k^)\frac{q_1 q_2}{56\sqrt{14}\pi\epsilon_0} (2\hat{i} - \hat{j} + 3\hat{k}) (c) q1q256πϵ0(j^−2i^−3k^)\frac{q_1 q_2}{56\pi\epsilon_0} (\hat{j} - 2\hat{i} - 3\hat{k}) (d) q1q25614πϵ0(j^−2i^−3k^)\frac{q_1 q_2}{56\sqrt{14}\pi\epsilon_0} (\hat{j} - 2\hat{i} - 3\hat{k})
