A capacitor C in series with inductor L (LC circuit) oscillates with frequency:
A1/(2π sqrt(LC))
Bsqrt(LC)
C1/(LC)
DLC
Answer & Solution
Correct answer: A. 1/(2π sqrt(LC))
f = 1/(2π sqrt(LC)). Same form as mechanical SHM (replace k with 1/C, m with L). Energy oscillates between capacitor (electric) and inductor (magnetic).
