Two isolated conducting spheres

S_1

and

S_2

of radius

\frac{2}{3}R

and

\frac{1}{3}R

have

12\text{ }\mu\text{C}

and

-3\text{ }\mu\text{C}

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

S_1

and

S_2

are respectively: (1)

4.5\text{ }\mu\text{C}

on both (2)

+4.5\text{ }\mu\text{C}

and

-4.5\text{ }\mu\text{C}

(3)

3\text{ }\mu\text{C}

and

6\text{ }\mu\text{C}

(4)

6\text{ }\mu\text{C}

and

3\text{ }\mu\text{C}
