Answer» Option(a) momentum The dimension of Plank's contant can be obtained from any of the equations in which it appears, e.g. h = E/ν, λ = h/p, etc. [h] = [ML^2T^−1] _____________(1) Angular momentuml=rxp [l] = [r] [p] = [L] [M LT^−1] = [ML^2 T^−1] _____________(2) Compare Eqs. (1) and (2). See that both the Planck's constant and angular momentum have the same dimensions. |
