Please solve Parts (c) & (d)

A rectangular loop forms an LC circuit.
The left side of the loop contains a
čapacitor C carrying a charge Q writh
the pasitively charged plate above the
negatively charged plate. The right side
of the loop contains an inductor L. The
bottom side of the loop contains an open
switch S.
