Question

In the figure below, let R = 7.00 Ω, L = 2.30 mH, and C = 1.65 µF.

The circuit is a rectangular loop with a vertical wire in the middle that extends from the bottom side of the loop to almost reach the top side, ending at point b below the top side. The left side contains a battery of emf ℰ with the positive terminal above the negative terminal. The right side contains a capacitor C. The top side, from left to right, contains point a and a switch S in contact with point a. The vertical wire contains, from top to bottom, point b, an inductor L, and a resistor R.
(a) Calculate the frequency of the damped oscillation of the circuit when the switch is thrown to position b.

(b) What is the critical resistance for damped oscillations?
