Show that the magnitude of torque = magnitude of force x moment arm. Also show that only the angular component of the force is responsible for producing torque.

Magnitude refers to the size or amount of a quantity, regardless of its direction, often used to describe scalar and vector quantities. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
