Multiple Choice
A conducting sphere of radius 20 cm has a charge Q placed on it producing a field of magnitude E0 at its surface. More charge is added to the surface until the magnitude of the field at the surface is 2 E0. If the potential at the surface was V0 when the field was E0, what is the potential when the field is 2 E0?
A) V0/2
B) 2 V0
C) 4 V0
D) 5 V0
E) 16 V0
