  • The figure represents variation of peak current with applied frequency <img alt="\nu" src="https://entranceco

The figure represents variation of peak current \i_{0} with applied frequency \nu of the AC source of three different LCR circuits having different resistances. The value of inductance L and capacitance C are same for all the three circuits.

Question

If \mathrm{R}_{\mathrm{l}}=1 \Omega, \mathrm{R}_2=5 \Omega, \mathrm{R}_3=10 \Omega \text { and } \mathrm{L}=\frac{900}{\pi} \mathrm{mH}, \mathrm{C}=\frac{40}{\pi} \mu \mathrm{F} ,then the frequency with which energy oscillates between Electric Field Energy and Magnetic Field Energy, is

Option: 1

\frac{1}{4 \pi \sqrt{L C}}


Option: 2

\frac{1}{\pi \sqrt{L C}}


Option: 3

\frac{1}{2 \pi \sqrt{L C}}


Option: 4

the energy in the electric field does not oscillate
