Question
Which of the following are the correct S.I. units of the quantities indicated? I. Ns (Momentum) II. Nm (Work) III. Watt/s (Power) IV. kgm/s² (Force).
Correct Answer
Option C is the correct answer.
Detailed Explanation
I. Ns = kg·m/s, which is momentum (correct). II. Nm = J, which is work (correct). III. Watt/s is not the SI unit of power; power is Watt (J/s). IV. kgm/s² = N, which is force (correct). So I, II, and IV are correct.
Hint
Check each unit against the definition of the quantity.
