A charge is uniformly distributed on the surface of a spherical rubber balloon. As it is blown up, the total…
- decreases
- increases
- remains unchanged
- becomes zero
Solution
The total electric flux through a closed surface is determined by Gauss's Law: $\Phi_E = \frac{Q_{\text{enc}}}{\epsilon_0}$.
As the balloon expands, the charge $Q_{\text{enc}}$ on its surface remains constant, while $\epsilon_0$ is a fixed constant.
Therefore, the electric flux $\Phi_E$ remains unchanged.
Final answer: C
