Pick an option to check your answer.
Answer & Solution
Correct Answer
(A) Statement \(I\) is true but Statement \(II\) is false
Step-by-step Solution
Detailed explanation
\( {[\mathrm{h}]=\mathrm{ML}^2 \mathrm{~T}^{-1}} \)
\( {[\mathrm{~L}]=\mathrm{ML}^2 \mathrm{~T}^{-1}} \)
\( {[\mathrm{P}]=\mathrm{MLT}^{-1}} \)
\( {[\tau]=\mathrm{ML}^2 \mathrm{~T}^{-2}}\)
(Here \(\mathrm{h}\) is Planck's constant, \(\mathrm{L}\) is angular momentum, \(\mathrm{P}\) is linear momentum and \(\tau\) is moment of force)
