Question

Answer this question correctly plzzz???

Answer 1

Answer:

Option(A)

Explanation:

As initially charge is maximum. So,

q = q₀ cosωt

=> i = dq/dt = -ωq₀ sinωt

Given,

Energy stored in inductor is equal to energy stored in capacitor.

∴ (1/2) LI² = q²/2C

=> (1/2) * L(ωq₀ sinωt)² = (q₀ cosωt/2C)²

But,

ω = 1/√LC

=> tan ωt = 1

=> ωt = π/4

⇒ t = (π/4ω)

=> t = (π/4) √LC

Hope it helps!
