Question

Suppose a point charge is located at the center of a spherical surface. The electric field at the surface of the sphere and the total flux through the sphere are determined. Now the radius of the sphere is halved. What happens to the flux through the sphere and the magnitude of the electric field at the surface of the sphere

Answer 1

The magnitude of flux remains the same, and the field increases.

Step-by-step explanation:

This is because the number of field lines leaving the sphere remains constant and the electric field increases because the line density increases
