Application +4 | -1
Time (T), velocity (C) and angular momentum (h) are chosen as fundamental quantities instead of mass, length and time. In terms of these, the dimensions of mass would be :
View answer and explanation
Correct option: A
[M]=[T−1C−2 h][\mathrm{M}]=\left[\mathrm{T}^{-1} \mathrm{C}^{-2} \mathrm{~h}\right]
Option A ([M]=[T−1C−2 h][\mathrm{M}]=\left[\mathrm{T}^{-1} \mathrm{C}^{-2} \mathrm{~h}\right]) is correct because by expressing mass in terms of time, velocity, and angular momentum, we can derive the correct dimensional formula using the definitions of these quantities.
