A positively-charged rod is held close to, but not touching, an isolated metal sphere. Which diagram shows the charges that are induced on the sphere?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Adiagram showing negative charges accumulated on the left side of the sphere (near the rod) and positive charges on the right side.

Bdiagram showing positive charges accumulated on the left side of the sphere (near the rod) and negative charges on the right side.

Cdiagram showing uniformly distributed positive charges on the sphere.

Ddiagram showing uniformly distributed negative charges on the sphere.

✓ Correct answer

D: diagram showing uniformly distributed negative charges on the sphere.
