Question

Which of the following is/are correct about total flux through a sphere of radius r? I. It is constant outside and concentrically around a point charge II. It is independent of distance from the charged sphere III. Total flux is independent of the surface area
Options
A I only
B II only
C I and II only
D I, II and III
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

By Gauss's law, Phi = Q_enclosed/eps0 - this depends ONLY on the enclosed charge, not on the radius, distance, or area of the Gaussian surface. So all three statements (I, II, III) are correct.

Hint

By Gauss's law, Phi = Q_enclosed/eps0 - this depends ONLY on the enclosed charge, not on the radius, distance, or area of the Gaussian surface.
