Question

If a body is charged by rubbing it, its weight
(a) remains precisely constant
(b) increases slightly
(c) decreases slightly
(d) may increase slightly or may decrease slightly

Answer 1

Answer:

(c) Decrease slightly

Answer 2

Answer is Option (d)

Explanation:

• 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.
• The gain of electrons increases the weight of a body slightly and loss of electrons reduces the weight slightly.
• That Means Number of Electrons is directly proportional to Weight of substance.

(d) may increase slightly or may decrease slightly
