Question: What is the dimension of torque?
- a) ML²T⁻²
- b) ML⁻²T⁻²
- c) MLT⁻¹
- d) ML²T⁻¹
ANSWER: a) ML²T⁻²
EXPLANATION:
The dimension of torque is a) ML²T⁻². Torque is a measure of the twisting or rotational force acting on an object. It is defined as the product of force and the perpendicular distance from the axis of rotation to the line of action of the force. The dimensions of force are MLT⁻², and the dimensions of the perpendicular distance are L. Multiplying these dimensions together gives us ML²T⁻², which represents the dimension of torque.
