Question:
The dimensional formula of angular momentum is
The dimensional formula of angular momentum is
Updated On: Jun 9, 2024
- $[ML^2T^{-2}]$
- $[ML^{-2}T^{-1}]$
- $[MLT^{-1}]$
- $[ML^2T^{-1}]$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Angular momentum $L$ = Moment of inertia $I \times$ Angular velocity $\omega$.
$\therefore$ Dimensional formula $L=[ML^2][T^{-1}]$
$ =[ML^2T^{-1}]$
$\therefore$ Dimensional formula $L=[ML^2][T^{-1}]$
$ =[ML^2T^{-1}]$

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

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.
