A) Planck's constant and angular momentum
B) Work and energy
C) Pressure and Young's modulus
D) Torque of force and moment of inertia
Correct Answer: D
Solution :
Planck's constant\[h=\frac{E}{v}=\frac{[M{{L}^{2}}{{T}^{-2}}]}{[{{T}^{-1}}]}=[M{{L}^{2}}{{T}^{-1}}]\] Angular momentum \[L=I\omega [M{{L}^{2}}][{{T}^{-1}}]=[M{{L}^{2}}{{T}^{-1}}]\] Work and energy \[=F.d=[ML{{T}^{-2}}][L]=[M{{L}^{2}}{{T}^{-2}}]\] pressure \[=\frac{F}{A}=\frac{[ML{{T}^{-2}}]}{[{{L}^{2}}]}=[M{{L}^{-1}}{{T}^{-2}}]\] Young's modulus \[Y=\frac{FL}{Al}=\frac{[ML{{T}^{-2}}][L]}{[{{L}^{2}}][L]}\] \[=[M{{L}^{-1}}{{T}^{-2}}]\] Torque \[\tau =F.d=[M{{L}^{2}}{{T}^{-2}}]\] Moment of inertia \[I=M{{R}^{2}}=[M{{L}^{2}}{{T}^{0}}]\]
