Question

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

Answer 1

HEY MATE !!!

________________________________________

when a body is charged its mass neither increase nor decrease .


it remains constant .


because of following reason :-

1) IN this process of charge of a body either gains or loss electorn to get the positive or negative charge but transfer of electron is not bought any disturbance / obstacles .


2). other reasons is that mass of electron is very smaller as if we go to compare it to the charge ..



this is reason that mass neither increase nor decrease when a body is charged .


hope it helps!!!!!!

Answer 2

Correct Option is C: remains constant.

Explanation:
****************

A body can be charged either by
---> Friction
--> Conduction
---> Induction.

An object acquires charge only by transfer of electrons.
Positive charge by loosing electrons
Negative charge by gaining electron..
As electrons are very very light compared to neutron and proton.
Hence transfer of electrons to acquire charge will not affect it's mass.
As atomic mass ( mass of an object) is sum of neutrons and protons.

Conclusion: when a body is charged: Mass remains constant .
