If some charge is given to a solid metallic sphere, the field inside remains zero and by Gauss's law all the charge resides on the surface. Suppose now that Colomb's force between two charges varies as `1//r^(3)`. Then, for a charged solid metallic sphere

Options

A. field inside will be zero and charge density inside will be zero.
B. field inside will not be zero and charge density inside will not be zero.
C. field inside will not be zero and charge density inside will be zero.
D. field inside will be zero and charge density inside will not be zero.

Answer

D
