Statement I : Planck's constant and angular momentum have same dimensions.\ Statement II : Linear m

Question

Statement I : Planck's constant and angular momentum have same dimensions.\ Statement II : Linear momentum and moment of inertia have same dimensions.\

Professor PC Thomas Classes · Answer

(b) : Plank's constant and angular momentum have same dimensions as, $L=m v r=n \hbar$. Dimension of linear momentum, $[P]=\left[\mathrm{MLT}^{-1}\right]$ Dimension of moment of inertia $(I)=\left[\mathrm{ML}^2\right]$ Hence, statement II is incorrect.
