Question

If a body is charged by rubbing it, its weight :

• A. Remains precisely constant
• B. Increase slightly
• C. Decrease slightly
• D. May increase slightly or may decrease slightly

Answer 1

The correct option is D May increase slightly or may decrease slightly

$\bullet$ On rubbing electrons transfer from one body to another body because of friction.
$\bullet$ If the body gains electrons, then its weight increases slightly. Since electrons has some mass.
$\bullet$ If the Body looses electrons, then its weight decreases slightly.
$\bullet$ Hence, Option D is correct.
