An initially uncharged hollow metallic sphere with radius of 5 cm has a small object with a charge of -10 µC carefully placed at the center of the sphere through a hole in the latter's surface. What charge resides inner surface of the sphere?

Question

Quizplus · Accepted Answer

The charge on the inner surface of the sphere will be +10 µC to balance the -10 µC charge placed at the center, ensuring the electric field inside the conductor is zero.
