Vedclass · Answer

(B) The dimensional formulas are calculated as follows:$(A)$ Planck's constant $(h)$: From $E = h
u$,we have $h = E / 
u$. The dimensions of energy $E$ are $[M^1 L^2 T^{-2}]$ and frequency $
u$ are $[T^{-1}]$. Thus,$[h] = [M^1 L^2 T^{-2}] / [T^{-1}] = [M^1 L^2 T^{-1}]$. This matches $III$.$(B)$ Stopping potential $(V_s)$: From $E = qV$,we have $V = E / q$. The dimensions of energy $E$ are $[M^1 L^2 T^{-2}]$ and charge $q$ are $[A^1 T^1]$. Thus,$[V_s] = [M^1 L^2 T^{-2}] / [A^1 T^1] = [M^1 L^2 T^{-3} A^{-1}]$. This matches $IV$.$(C)$ Work function $(\phi)$: Work function is a form of energy. Thus,$[\phi] = [M^1 L^2 T^{-2}]$. This matches $I$.$(D)$ Momentum $(p)$: Momentum $p = mv$. The dimensions are $[M^1] 	imes [L^1 T^{-1}] = [M^1 L^1 T^{-1}]$. This matches $II$.Therefore,the correct matching is $A-III, B-IV, C-I, D-II$.
