Units & Dimensions question from JEE Main 2026 (28 Jan, Shift 2)

Answer: (b)

1. Viscosity $= [\mathrm{ML^{-1}T^{-1}}]$ → IV.
2. Surface tension $= F/l = [\mathrm{ML^0T^{-2}}]$ → III.
3. Pressure $= F/A = [\mathrm{ML^{-1}T^{-2}}]$ → I.
4. Surface energy is an energy $= [\mathrm{ML^2T^{-2}}]$ → II.
5. So the answer is (b) A-IV, B-III, C-I, D-II.
