Point $P$ is outside a spherical charged balloon that someone is inflating. The balloon's center remains fixed relative to $P$. The electric field's magnitude $|\vec{E}|$ at $P$ grows as the balloon's charged surface approaches.

Question

Quizplus · Accepted Answer

The electric field magnitude $|\vec{E}|$ at point $P$ remains constant because the total charge on the balloon does not change, and the distance from the center of the balloon to $P$ remains the same.
