Q. A point charge q = -8nC is located at the origin. The electric field (in NC-1) vector at the point x = 1.2m, y= -1.6m, as shown in figure, is
(a) $ \Large -14.4\hat{i} + 10.8\hat{j} $
(b) $\Large -14.4\hat{i} – 10.8\hat{j} $
(c) $ \Large -10.8\hat{i} + 14.4\hat{j} $
(d) $\Large -10.8\hat{i} – 14.4\hat{j} $
Ans: (c)
