Question

31.41 -- CP A parallel-plate capacitor having square plates 4.50 cm on each side and 8.00 mm apart is placed in series with the fol- lowing: an ac source of angular frequency 650 rad/s and voltage amplitude 22.5 V; a 75.0-12 resistor, and an ideal solenoid that is 9.00 cm long, has a circular cross section 0.500 cm in diameter, and carries 125 coils per centimeter. What is the resonance angu- lar frequency of this circuit? (See Exercise 30.15.)
