Question

Charge density on the surface of a conducting solid depends upon:

• A. The density of the conductor
• B. The shape of the conductor
• C. The size of the conductor
• D. The age of the conductor
• E. The substance of the conductor

Answer 1

Answer: (C)

The size of the conductor

The charge density on the surface of a conductor of surface area $A$, when a charge of $q$ is given to conductor is given by:

$\sigma =q/A$

Charge density depends on amount of charge and surface area of conductor or size of conductor.
