NEET2019PhysicsUnits and DimensionsActual
If mass ( M ) , distance ( L ) and time ( T ) are fundamental quantities, then find dimension of torque.
Options
- A[ ML ^2 ~T ⁻² ]
- B[ MLT ⁻² ]
- C[M L T]
- D[M L^2 T ]
Correct answer
A. [ ML ^2 ~T ⁻² ]
Step-by-step solution
Dimension of torque aligned & = F r = [ MLT ⁻² ][ L ] & = [ ML ^2 ~T ⁻² ] aligned
