A) angular momentum
B) torque
C) coefficient of thermal conductivity
D) gravitational constant
Correct Answer: D
Solution :
Dimensional formula of angular momentum \[(L)=[M{{L}^{2}}{{T}^{-1}}]\] Torque \[(\tau )=[M{{L}^{2}}{{T}^{-2}}]\] Coefficient of thermal conductivity \[(K)=[ML{{T}^{-3}}{{K}^{-1}}]\] Gravitational constant \[(G)=[{{M}^{-1}}{{L}^{3}}{{T}^{-2}}]\] Thus, gravitational constant has negative ' dimension of mass.
