Question

22.
h
is the dimension of
211
(1) Velocity
(2) Momentum
(3) Energy
(4) Angular momentum​

Answer 1

Answer:

(4) Angular momentum

Step-by-step explanation:

hope it helps yOu ☺️☺️

Answer 2

Answer:

We know that E=hν

where dimensions of Energy, E are ML

2

T

−2

and dimensions of frequency are inverse of Time Period, i.e. T

−1

Thus, ML

2

T

−2

=[h]T

−1

or, [h]=ML

2

T

−1

Now, angular momentum, L=Iω

where units of omega are inverse of time (rad/sec, where radian is dimensionless).

Units of I are ML

2

(because I is of the form kMx

2

)

Thus [L]=ML

2

T

−1
