MHT CET 2024 Physics question

A spherical rubber balloon carries a charge, uniformly distributed over the surface. As the balloon is blown up and increases in size, the to electric flux coming out the surface

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

Answer: (D)

Solution

By Gauss's law the electric flux through any closed surface enclosing the charge is , which depends only on the enclosed charge and the medium, not on the size or shape of the surface. When the balloon is blown up, the charge on it stays the same, so the
