- $ \frac{1}{RC}$
- $ \frac{ R}{L}$
- $ \frac{1}{ \sqrt{ LC}}$
- $ \frac{C}{L}$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
CR and $ \frac{L}{R}$ both are time constants. Their unit is second.
$\therefore \frac{1}{CR} \, and \, \frac{R}{L}$ have the SI unit (second $)^{ - 1}$. Further.
resonance frequency $\omega = \frac{1}{ \sqrt{ LC}}$
$\therefore \frac{1}{CR} \, and \, \frac{R}{L}$ have the SI unit (second $)^{ - 1}$. Further.
resonance frequency $\omega = \frac{1}{ \sqrt{ LC}}$

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.
