A spherical rubber balloon carries a charge, uniformly distributed over the surface. As the balloon is blown up and increases in size, the total electric flux coming out of the surface
Becomes zero
Increases
Decreases
Remains unchanged
Solution
Total electric flux through the surface $=\frac{\mathrm{q}}{\varepsilon_0}$.
As charge remains unchanged when size of balloon increases, electric flux through the surface remains unchanged.
