Chapter 6, Problem 1MCQ

To determine

The correct unit for linear momentum.

Answer to Problem 1MCQ

Option (b).

Explanation of Solution

Write the expression for linear momentum

    $p=mv$

Here, $p$ is the linear momentum, $m$ is the mass and $v$ is the velocity.

The SI unit of mass is kg and that of velocity is m/s.

Conclusion:

The SI unit of linear momentum is kg·m/s. Thus, option (b) is correct.

N/m is the unit of acceleration. Thus, option (a) is incorrect.

N/s doesn’t have the same dimension as kg·m/s. Thus, option (c) is incorrect.

All options aren’t correct. Thus, option (d) is incorrect.
