Question 942: Electrostats & Capacitance

Question

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

Accepted Answer

According to GaussÃ¢ÂÂs law
$${\phi _E} = {{{Q_{enclosed}}} \over {{\varepsilon _0}}}$$
If the radius of the Gaussian surface is doubled, the outward electric flux will remain the same. This is because electric flux depends only on the charge enclosed by the surface.
