MHT CET 2026 Physics question

If the radius of the spherical Gaussian surface is increased then the electric flux due to a point charge enclosed by the surface

(A)increases
(B)remains unchangedCorrect
(C)is zero
(D)decreases

Answer: (B)

Solution

By Gauss's law the electric flux through any closed surface depends only on the charge enclosed: . Increasing the radius of the spherical Gaussian surface does not change the enclosed charge, so the flux remains unchanged, option (B). Although
