Question:
The only mechanical quantity which has negative dimension of mass is
The only mechanical quantity which has negative dimension of mass is
Updated On: Jul 11, 2024
- angular momentum
- torque
- coefficient of thermal conductivity
- gravitational constant
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Dimensional formula of angular momentum
$(L)=\left[M L^{2} T^{-1}\right]$
Torque $(\tau)=\left[M L^{2} T^{-2}\right]$
Coefficient of thermal conductivity
$(k)=\left[M L T^{-3} K^{-1}\right]$
Gravitational constant
$(G)=\left[M^{-1} L^{3} T^{-2}\right]$
Thus. gravitational constant has negative dimension of mass.

Physical World
The physical world includes the complications of the natural world around us. It is a type of analysis of the physical world around us to understand how it works. The fundamental forces that control nature are:
- Gravitational Force is a universal force that exists as an outcome of mutual attraction between any two objects with respect to their masses.
- Electromagnetic Force can be understood as the force that is present between the charged particles. The force is stated by Coulomb’s law.
- Strong Nuclear Force is the force that ties the protons and neutrons in a nucleus. Of all the elemental forces in nature, a strong nuclear force is the strongest as its name suggests.
- Weak Nuclear Force can only be noticed in some of the nuclear processes such as the beta decay of the nucleus.
