A24.0@mf capacitor is charged by a 170.0-v power supply, then disconnected from the power and connected in series with a 0.210-mh inductor. calculate: (a) the oscillation frequency of the circuit; (b) the energy stored in the capacitor at time t = 0 ms (the moment of connection with the inductor); (c) the energy stored in the inductor at t = 1.35 ms.

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

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
