A hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre:

Correct Answer: C — Zero for r < R, decreases as r increases for r > RKey Concept: By Gauss's law, the electric field at any point depends on the charge enclosed within a Gaussian surface of radius r.Case 1 — Inside the shell (r < R):A Gaussian surface inside the shell encloses zero charge.By Gauss's law: E × 4πr² = Qenclosed/ε0 = 0Therefore, E = 0 for all r < R.Case 2 — Outside the shell (r > R):All charge Q is enclosed. The sphere behaves like a point charge:E = kQ/r² = Q/(4πε0r²)E ∝ 1/r², so E decreases as r increases.
