Question

The mismatch between the physical quantity and the dimensional formula in the following is

• A. Force: $MLT^{-2}$
• B. Torque: $ML^{2}T^{-1}$
• C. Pressure: $ML^{-1}T^{-2}$
• D. Heat energy: $ML^{2}T^{-2}$
• E. Thermal conductivity: $MLT^{-3}K^{-1}$

Hint:

Logic Tip: Torque and Work (Energy) share the exact same dimensional formula $[ML^2T^{-2}]$. If you know Heat Energy is $[ML^2T^{-2}]$, then Torque must also be $[ML^2T^{-2}]$. The given $T^{-1}$ instantly stands out as wrong.

Answer 1

The Correct Option is B
