In a chamber, three spheres carry charges + 3 e, + 5 e and – 3 e. They came in contact for a moment and got separated. Which one of the following are possible values for the final charges on the spheres?
Total initial charge:
(+3e)+(+5e)+(−3e)=5e
When conductors touch, charge redistributes while conserving total charge. The total charge remains 5e, so the final charges must sum to 5e.
Now, checking the options: Possible answers: (b) and (c).

The correct answer is (d) +5e, -8e, +7e. When conductors come in contact, charge redistributes while conserving total charge. The initial total charge is (+3e) + (+5e) + (-3e) = +5e. Among the given options, only (d) +5e, -8e, +7e maintains this total charge, satisfying charge conservation and possible redistribution after separation.
