The SI unit of torque is-

The SI unit of torque is- Correct Answer Nm

The correct answer is option 1) i.e. Nm.

CONCEPT:

  • Torque: It is a type of twisting force that causes the rotation of an object.
    • Torque is the measure of force that can cause an object to rotate.
    • It is also called a moment of force.
    • Torque is the product of force(F) and the perpendicular distance of force from point of rotation(S).

It is given by the formula:

τ = F × S

EXPLANATION:

  • Since torque is the product of force and distance, its SI unit will be

τ = F × S = N × m

  • Hence, the SI unit of torque is Nm.
