Can anybody understand/know this problem?

[assa123]

Here is the circuit and the rectangular waveform of current source. frequency is 500Hz

Does anybody know how to sketch and label the voltage across the capacitor?

Also, How to get the magnitude of the fundamental component of capacitor voltage? (maybe using Fourier transformer?)

THanks for helping!
Thanks a lot!

If you look at the circuit and convert the resistor and current source from a norton model to a thevenin model, it might make things easier for you.
