A charge Q is enclosed by a Gaussian spherical surface of radius R

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

Options

(a) increase four times
(b) be reduced to half
(c) remain the same
(d) be doubled

Correct Answer:

remain the same

Explanation:

By gauss’s therorem, ? = Qin / ?￢ﾂﾀ, Thus the net flux depends onlu on the charge enclosed by the surface. Hence, there will be no oeffect on the net flux if the radius of the surface is doubled.
