Question

LC circuit oscillates analogously to mass-spring SHM. Angular frequency is:
  1. A
    1/√(LC)
    Correct
  2. B
    √(LC)
  3. C
    √(L/C)
  4. D
    1/LC

Correct answer

1/√(LC)

Explanation

LC circuit: ω = 1/√(LC). Analogy: L↔m (inertia), C↔1/k (compliance), charge↔displacement, current↔velocity.
