NEET Physics Question - Electrostatics

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): When a neutral body is positively charged, its mass decreases.

Reason (R): A body acquires positive charge when it loses electrons.

In the light of the above statements, the correct option is

Both (A) and (R) are true and (R) is the correct explanation of (A)

Both (A) and (R) are true but (R) is not the correct explanation of (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Charging a body positively involves removing electrons. Since electrons have mass, removing them decreases the body's mass. Thus, both statements are true and Reason is the correct explanation.
