A point charge +q is placed at the origin. A second point charge +9 q is placed at $(d, 0, 0)$ in Cartesian coordinate system. The point in between them where the electric field vanishes is :

Options:

Answer:

Solution:

Let $E_{p} = 0$
$∴ \frac{kq}{x ^{2}} = \frac{k 9 q}{( d - x ) ^{2}} \Rightarrow \frac{d - x}{x} = 3 \Rightarrow x = \frac{d}{4}$
$∴$ co-ordinate of P is $(\frac{d}{4}, 0, 0)$
