Which of the statements given above is/are correct?
1. The inertia of a body depends on its mass.
2. Momentum of a body is a scalar quantity.
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: (A) 1 only
Inertia is the tendency of a body to resist a change in its state of motion, and its measure is the mass; so statement 1 is correct. Momentum p = mv is a vector because velocity is a vector, and it points in the direction of velocity; so statement 2 is wrong. Hence only statement 1 is correct.
