medium
The fundamental physical quantities that have same dimensions in the dimensional formulae of torque and angular momentum are
AMass, time
BTime, length
CMass, length
DTime, mole
Solution
(c) Torque = $[M{L^2}{T^{ – 2}}]$,
Angular momentum = $[M{L^2}{T^{ – 1}}]$
So mass and length have the same dimensions
Angular momentum = $[M{L^2}{T^{ – 1}}]$
So mass and length have the same dimensions
