Q. A charge of $Q\ coulomb$ is placed on a solid piece of metal irregular shape. The charge will distribute itself
A) Uniformly in the metal object
B) Uniformly on the surface of the object
C) Such that potential energy of the system is minimised
D) Such that the total heat loss is minimised
Explanation
