Which of the statements given above is/are correct?
1. The action and reaction forces in Newton's third law act on the same body.
2. Mass of a body is a measure of its inertia.
Which of the statements given above is/are correct?
- A. 1 only
- B. 2 only
- C. Both 1 and 2
- D. Neither 1 nor 2
Show answer and solution
Answer: (B) 2 only
Action and reaction forces are equal and opposite but act on two different bodies, so they never cancel each other; statement 1 is false. Inertia is the tendency of a body to resist a change in its state of motion, and mass measures it, so statement 2 is true. Only statement 2 is correct.
