Question 89

Multiple Choice

A charge is placed on a spherical conductor of radius r1.This sphere is then connected to a distant sphere of radius r2 (not equal to r1) by a conducting wire.After the charges on the spheres are in equilibrium,


A) the electric fields at the surfaces of the two spheres are equal.
B) the amount of charge on each sphere is q/2.
C) both spheres are at the same potential.
D) the potentials are in the ratio V2V1=q2q1\frac { V _ { 2 } } { V _ { 1 } } = \frac { q _ { 2 } } { q _ { 1 } } .
E) the potentials are in the ratio V2V1=r2r1\frac { V _ { 2 } } { V _ { 1 } } = \frac { r _ { 2 } } { r _ { 1 } } .
