Question

Which is correct about total flux through a sphere of radius r around a point charge? I. Constant outside and concentric; II. Independent of distance; III. Does not obey inverse square law.
Options
A I only
B II only
C I and II only
Correct Answer
D I, II and III
Correct Answer

Option C is the correct answer.

Detailed Explanation

Flux = Q/ε₀ constant, independent of r (I and II true). It does obey Gauss's law, which is inverse square based, but flux itself is constant. Statement III is false.

Hint

Gauss's law: Φ = Q/ε₀.
