Two point charges $+ 8 q$ and $- 2 q$ are located at $x = 0$ and $x = L$ respectively. The location of a point on the $x$ axis at which the net electric field due to these two point charges is zero is

Options:

Answer:

Solution:

$- \frac{k 2 q}{( x - L ) ^{2}} + \frac{k 8 q}{x ^{2}} = 0$ $\Rightarrow x = 2 L$
