Dear Student
Total energy
U= 1/2(Q^2​/C)
Let at any instant the charge on capacitor beQ’
∴Electrical energy = Magnetic energy= ((Q’)^2​)/2C
So, new total energy=((Q’)^2​)/2C +((Q’)^2​)/2C =Q′^2​/C
According to question
1/2(Q^2​/C)=Q′^2​/C
Q′= Q/​√2
Magnetic energy= ((Q’)^2​)/2C= Q^2/4C
(1/2)L(I^2) =Q^2/4C

I = Q / √(2LC)


Thanks
