Question

The SI unit of moment of force is:

• A. newton-metre
• B. newton-centimetre
• C. dyne-metre
• D. dyne-centimetre

Answer 1

The correct option is A

newton-metre

1. The moment of force is the product of force and perpendicular distance from the point of application of force to the axis of rotation.
2. SI unit of forces is Newton.
3. SI unit of distance is meter.
4. So, the unit of moment of force is Newton-metre
5. Hence, option (A) is the correct answer.
