The physical quantity having the same dimensions as Planck's constant \(h\) is
- A Boltzmann constant
- B force
- C linear momentumi
- D angular momentum
Answer & Solution
Correct Answer
(D) angular momentum
Step-by-step Solution
Detailed explanation
Dimensional formula of Planck's constant \(=\left[\mathrm{M}^{1} \mathrm{~L}^{2} \mathrm{~T}^{-1}\right]\) Similarly, Boltzmann constant is given \[ K=\frac{\text { Energy }}{\text { Temperature }} \] \(\therefore\) The dimension of \(K\) is…
