Question

Why is static electric potential of the whole volume of the charged conductor equivalent to that on its surface?

Answer 1

Answer:

As inside the conductor the electric field is zero ,so no work is done against electric field to bring a charge particle from one point to another.

Therefore the potential inside the surface is ZERO.

V=W/q

[W=0 , q not equal to 0]

V=0

Answer 2

Answer:

as electric field inside the conductor is zero so there is no work done in moving a small test charge within the conductor. therefore there is no potential difference between any two points inside the conductor that is electrostatic potential is constant throughout the volume of the conductor.
