PhysicsMediumsingle choice

In the $LC$ circuit shown below, the current is in direction as shown and the charges on the capacitor plates have the sign as shown. At this instant

Options:

Answer:

Solution:

As clearly ‘ $Q$ ’ is increasing so electric field energy in capacitor must be increasing. And hence, magnetic field energy in inductor must be decreasing. So $I$ is decreasing.
