Question

The dimensional formula for plank's constant and angular momentum are


A
[ML2T2]and[MLT1]
loader
B
[ML2T1]and[ML2T1]
loader
C
[ML3T1]and[ML2T2]
loader
D
[ML2T1]and[ML2T2]
loader

Solution

The correct option is B $$\left[ M{ L }^{ 2 }{ T }^{ -1 } \right] and \left[ ML^{ 2 }{ T }^{ -1 } \right] $$
Planck's constant, symbolized h, relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation.

$$h=\dfrac Ev=\dfrac{[ML^2T^{-2}]}{[T^{-1}]}=[ML^2T^{-1}]$$

Angular momentum $$=$$ Moment of inertia $$\times$$ Angular velocity (Angular momentum)

$$=[ML^2][T^{-1}]=[ML^2T^{-1}]$$

So, correct answer is option (B).
