Two isolated conducting spheres S1 and S2 of radius 32R and 31R have 12μC and −3μC charges, respectively, and are at a large distance from each other. They are now connected by a conducting wire. A long time after this is done the charges on S1 and S2 are respectively:
a. 4.5μC on both
b. +4.5μC and −4.5μC
c. 3μC and 6μC
d. 6μC and 3μC
