Electric Flux & Gauss's Law

The electric flux over a sphere of radius ' $r$ ' is ' $\phi$ '. If the radius of the sphere is doubled without changing the charge, the flux will be

Show answer and solution

Answer: (c)

Gauss's law: $\phi = \dfrac{q}{\varepsilon_0}$ , independent of the radius of the sphere.
Charge unchanged, so flux stays $\phi$ .
So the answer is (c) $\phi$ .
