Units & Dimensions question from NEET 2000 (AIPMT)

Answer: (b)

1. Force: $\mathrm{MLT^{-2}}$; impulse $= Ft$: $\mathrm{MLT^{-1}}$. Not equal.
2. Energy = torque ($\mathrm{ML^2T^{-2}}$); angular momentum = $h$ ($\mathrm{ML^2T^{-1}}$); elastic modulus = pressure ($\mathrm{ML^{-1}T^{-2}}$).
3. So the answer is (b).
