Two isolated conducting spheres S1 and S2 of radius 2/3R and 1/3 R 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 :
(1) 6 μC and 3μC
(2) 4.5 μC of both
(3) +4.5 μC and –4.5 μC
(4) 3 μC and 6 μC

Correct answer: (1) 6 μC and 3μC
Explanation:
Total charge = 12 – 3 = 9μC
If final charges are q1 and q2
q1/q2 = R1/R2 = 2/1
q1 = 6 μC
q2 = 3μC
