Q116 / 200 · NEET 2011 (Screening) · Physics

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

  • A
    be reduced to half
  • Correct answer
    B
    remain the same
  • C
    be doubled
  • D
    increase four times

Solution

Total flux $=\frac{\text { Net enclosed charge }}{\varepsilon_0}$ Hence, we can say the electric flux depends only on net enclosed charge by surface.

Hence, the correct answer is option: 'B'.
