- $ [ MLT^{ - 1} \theta^{ - 1} ] $
- $ [ MLT^{ - 3} \theta^{ - 1} ] $
- $ [ M^2LT^{ - 3} \theta^{ - 2} ] $
- $ [ ML^2T^{ - 2} \theta] $
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$ \Delta Q = KA \left( \frac{ T_1 - T_2 }{ L } \right) \Delta t $
or [ K ] = $ \frac{ [ ML^2 T^{ - 2} ] [ L ] }{ [ L^2 ] [ \theta ] [ T ] } $
$ [ MLT^{ - 3} \theta^{ - 1} ] $
or [ K ] = $ \frac{ [ ML^2 T^{ - 2} ] [ L ] }{ [ L^2 ] [ \theta ] [ T ] } $
$ [ MLT^{ - 3} \theta^{ - 1} ] $

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.
