Electric Flux & Gauss's Law

A charge Q is enclosed by a Gaussian spherical surface of radius R. If the radius is doubled, then the outward electric flux will

Show answer and solution

Answer: (c)

Flux $= \dfrac{Q}{\varepsilon_0}$ depends only on enclosed charge, not on $R$ .
Doubling the radius keeps $Q$ enclosed the same.
So the answer is (c) remain the same.
