Question:
The dimensions of impulse are equal to that of
The dimensions of impulse are equal to that of
Updated On: Jul 13, 2024
- pressure
- linear momentum
- force
- angular momentum
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Impulse = Force $\times$ Time.
Therefore dimensional formula of impulse
= Dimensional formula of force $\times$ Dimensional formula of time $= [MLT^{-2}] [T]$
$ = [MLT^{-1}]$ and dimensional formula of linear momentum
$[p] = MLT^{-1}$.
Therefore dimensional formula of impulse
= Dimensional formula of force $\times$ Dimensional formula of time $= [MLT^{-2}] [T]$
$ = [MLT^{-1}]$ and dimensional formula of linear momentum
$[p] = MLT^{-1}$.

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.
