The electric potential at the surface of a conducting,spherical shell of radius R is V > 0 relative to Earth ground.True or False?1. The magnitude of the electric potential at a distancer=2R from the center of the shell is V/2.2. The electric potential at the center of the shellrelative to Earth ground is V.3. The electric potential at the center of the shellrelative to Earth ground is 0.4. If an excess charge of +Q is placed on the shell, the electric potential inside the shell will increase.5. At all points inside the shell the electric potentialis the same.
