Question

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

G1 Physics · Accepted Answer

Step 1: Gauss law Φ = Q/ε₀ for any closed surface surrounding the same charge. Step 2: Changing radius modifies local E and area but not enclosed Q, hence outward electric flux remains Q/ε₀.
