Question

When a body is charged, its mass:
(A). Increase
(B). Decrease
(C). Remains same
(D). None of these

Answer 1

Hint: Mass of the body is its internal property. The mass of the object is the total mass of each particle inside the object. Mass of the object is not affected by gravity and other forces. The SI unit of the mass is kilogram.

Complete step-by-step answer:

Electric charge of the body causes it to experience the force when an electric field is applied to it. There are two types of charges:
Positive charge: when electron lost, the body developed positive charge
Negative charge: when electrons gained, the body developed negative charge.
The negative and the positive charges attract each other.

Charging of any body is the process of increasing or decreasing the number of electrons. The mass of the electrons is almost negligible. Thus, the mass of the body remains unaffected while charging or discharging the body.
Correct option is C.

Note: When electrons of the atoms are either donated or accepted. The number of the protons inside the atom changes. This results in the charging of the object.
Protons do not contribute in the charging and discharging process. The number of protons remains the same even after the object acquires charge.
