# Out of the following pair, which one does NOT have identical dimensions is A angular momentum and Planck's constant

Out of the following pair, which one does NOT have identical dimensions is

• A angular momentum and Planck's constant
• B impulse and momentum
• C moment of inertia and moment of a force
• D work and torque

$$\therefore$$ [I] = [ML2]
Moment of force, $$\overrightarrow \tau = \overrightarrow r \times \overrightarrow F$$
$$\therefore[\overrightarrow \tau ]=[L][ML{T^{ - 2}}]=[ML^{ 2}{T^{ - 2}}]$$
