A) linear momentum
B) angular momentum
C) Boltzmann constant
D) force
Correct Answer: B
Solution :
Dimensions of Plancks constant h \[=[M{{L}^{2}}{{T}^{-1}}]\] Dimensions of linear momentum \[=[ML{{T}^{-1}}]\] Dimensions of angular momentum \[=[M{{L}^{2}}{{T}^{-1}}]\] Dimensions of Boltzmann constant \[=[M{{L}^{2}}{{T}^{-2}}{{\theta }^{-1}}]\] Dimensions of force \[=[ML{{T}^{-2}}]\] Hence, it is obvious that dimensions of Plancks constant is same as that of angular momentum.
