MCQ
The fundamental physical quantities that have same dimensions in the dimensional formulae of torque and angular momentum are
- AMass, time
- BTime, length
- ✓Mass, length
- DTime, mole
✓
Answer
Correct option: C.
Mass, length
c
(c) Torque = $[M{L^2}{T^{ - 2}}]$,
(c) Torque = $[M{L^2}{T^{ - 2}}]$,
Angular momentum = $[M{L^2}{T^{ - 1}}]$
So mass and length have the same dimensions
