Question

Which of the following is a unit of moment of force?

• A. N-m
• B. N-kg²
• C. N-m²
• D. N-kg

Answer 1

The correct option is A

N-m

The magnitude of the moment of force about a point is defined as the product of the magnitude of the force and the perpendicular distance of the point from the line of action of the force. So, T = F $\times$ d. Now, the unit of force is Newton and distance has a unit of meter. So N-m is a unit of moment of force.
