Question

(i) when a body is charged, its mass (a) increases (b) decreases (c) remains constant (d) may increase or decrease.

Answer 1

C... remains constant

Answer 2

When a body is charged the mass of a body remains constant. Because the mass of the charged particles tends to zero and it is so considered to be negligible. Thus the introduction of electrons or the removal of electrons does not affect the mass of a body and thus the mass remains constant.
