An LCR circuit is equivalent to a damped pendulum In an LCR circuit the capacitor is charged to `Q_(0)` and then connected to the L and R as shown below : Thus potential energy stored in the capacitor and that in the inductor also oscillates between maximum value an zero with double the frequency.

If a student plots graphs of the square of maximum charge `(Q_("max")^(2))` on the capacitor with time (t) for two different values `L_(1) and L_(2) (L_(1) gt L_(2))` of L then which of the following reprersent this graph correctly ? (Plots are shematic and not drawn to scale )
