Dimensional Analysis

The mechanical quantity, which has dimensions of reciprocal of mass \( \text{M}^{-1} \) is
Torque
Gravitational constant
Angular momentum
Coefficient of thermal conductivity

Solution:

The dimension of the universal gravitational constant \(G\) is \([\text{M}^{-1}\text{L}^3\text{T}^{-2}]\). Therefore, its dimensions contain the reciprocal of mass.
