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
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.
