Physics · LAWS OF MOTION

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): To calculate the acceleration of a single body in a system, both action and reaction forces acting on that body must be added to give the net force. Reason (R): Action and reaction forces act simultaneously on two different bodies and never cancel each other on a single body. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is false but (R) is true.
4. (A) is true but (R) is false.
