The dimensional formula for Planck's constant and angular momentum are

• A

  $\left[{\mathrm{ML}}^2{ \mathrm{T}}^{-2}\right]and{\text{ [MLT ] }}^{-1}\text{ ]}$

• B

  $\left[{\mathrm{ML}}^2{ \mathrm{T}}^{-1}\right]and\left[{\mathrm{ML}}^2{ \mathrm{T}}^{-1}\right]$

• C

  $\left[{\mathrm{ML}}^3 \mathrm{T}\right]and\left[{\mathrm{ML}}^2{ \mathrm{T}}^{-2}\right]$

• D

  $\text{ [MLT] }and{\text{ [MLT }}^{-2}]$
