Question

In an oscillating lc circuit the maximum charge on the capacitor is q.The charge on the capacitor when the energy is stored equally between the electric and magnetic fields is.

Answer 1

LC Circuit oscillation s

Answer 2

The energy equally stored between both the field is Q/√2 .

Maximum charge on capacitor = q (Given)

The electric energy stored when energy in equally distributed, U'E = 1/2.q²/C

The energy stored in the capacitor when it is maximally charged, UE = 1/2.Q²/C

Thus,  

Ue = 2U'e

= q = Q/√2

Therefore, the energy equally stored between both the field is Q/√2 .
