Question
If a body is charged by rubbing it, its weight
Options
remains precisely constant
increases slightly
decreases slightly
may increase slightly or may decrease slightly
Solution
may increase slightly or may decrease slightly
If a body is rubbed with another body, it'll either gain some electrons from the other body and become negatively charged or it'll lose some electrons to the other body and become positively charged. Gain of electrons increases the weight of a body slightly and loss of electrons reduces the weight slightly.
