Question
The dimension of torque are :
Options
- A
(MLT)
- B
(M2 42 L)
- C
(ML2 T-2)
- D
(ML2 T2)
Explanation
The SI unit for torque is the Newton-metre or kgm2sec-2. Torque has the dimension of force times distance, symbolically T−2L2M. Although those fundamental dimensions are the same as that for energy or work, official SI literature suggests using the unit newton metre (N⋅m) and never the joule.
