Question

A solid sphere of radius $4a$ units is placed with its centre at origin. Two charges $-2q$ at $(-5a, 0)$ and $5q$ at $(3a, 0)$ is placed. If the flux through the sphere is $\frac{xq}{\in_0}$ , find $x$

Answer 1

The Correct answer is : 5

From Gauss law
$\phi=\frac{q_{enclosed}}{ε_0}=\frac{5q}{ε_0}$
