Question

The dimensional formula for Planck constant and angular momentum is:

Answer 1

[M L^2 T^-1]=dimensional formula of plancks constant and angular monentum

Answer 2

Dimensional formula for Planck constant and angular momentum is

A) Plank constant

Plank constant = Energy / Frequency

Energy = Kg m²/sec² = M¹L²T^-2

Frequency = 1/sec = M^0 L^0 T^-1

then Plank constant is M¹L²T^-2-(-1)

M¹L²T^-1

Angular momentum[w]

L = I w

I = m r²

I = kg . m²

Dimensional formula of angular momentum is M L²T^-1
