Explanation:
Answer:
Part a)
Part b)
U = 111 J
Explanation:
As we know that the capacitor is of capacitance
now the maximum charge on it
Part a)
Oscillation frequency of the charge is given as
Part b)
Now the equation of charge oscillation is given as
now current in the circuit is given as
now at t = 1.35 ms we have
So the energy stored in inductor is given as
