Electric Flux through the surface of a sphere which has constant charge at its center depends on:
Correct answer: C. The amount of charge inside the sphere
- A. The radius of the sphere
- B. The surface area of the sphere
- C. The amount of charge inside the sphere
- D. The amount of charge outside the sphere
Explanation
As per Gauss's theorem in electrostatics, the electric flux through a surface depends only on the amount of charge enclosed by the surface. It does not depend on size and shape of the surface. Therefore, electric flux through the surface is the same for all figures.

About Electric Field
An electric field is the force experienced per unit positive test charge, with the field of a point charge given by E = kQ/r² and directed away from positive charges or toward negative charges. Questions involve field lines, superposition and force on a charge, while electric field must be distinguished from electric potential.
