(A) Planck’s constant h=\frac{E}{v}

[h]=\frac{\left[\mathrm{M}^1 \mathrm{~L}^2 \mathrm{~T}^{-2}\right]}{\left[\mathrm{T}^{-1}\right]} \Rightarrow[h]=\left[\mathrm{M}^1 \mathrm{~L}^2 \mathrm{~T}^{-1}\right]

(B) Stopping potential V=\frac{W}{q}

[\mathrm{v}]=\frac{\mathrm{ML}^2 \mathrm{~T}^{-2}}{\mathrm{AT}} \Rightarrow[\mathrm{v}]=\left[\mathrm{ML}^2 \mathrm{~T}^{-3} \mathrm{~A}^{-1}\right]

(C) Work function  =\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]

(D) Momentum[\mathrm{P}]=\left[\mathrm{MLT}^{-1}\right]
