Choke coil | Oscillation in LC Circuit

The oscillation in LC, circuit is produced due to

The natural frequency (omega_(0)) of oscillations in LC circuit is given by

Choke coil is a series

Complete the following statement: When the current in an oscillating LC circuit is zero,

Show that n the free oscillations of an LC circuit, the sum of energies stored in the capacitor and and the inductor is constant in time.
