On charging a neutral balloon, its size
When a neutral balloon is charged, its size increases. This happens because like charges repel, causing the charged particles on the balloon’s surface to push apart. This increases the internal electrostatic pressure, slightly expanding the balloon. Thus, the correct answer is (a) Increases.

On charging a neutral balloon, its size increases due to electrostatic repulsion. The added charge causes like charges on the balloon’s surface to repel each other, leading to expansion. This effect is noticeable in flexible materials like balloons, where the repelling charges push outward, slightly increasing the overall size of the balloon.
