(adsbygoogle = window.adsbygoogle || []).push({}); Oscillation frequency

I'm not sure what to do for this question. I have found a few things of relevancy but i'm making the problem more complex than it really is?

A leyden jar of capacitance C=10^-9 farads is short circuited with a copper wire of self-inductance L=3 x 10^-7 and resistance R=5x10^-3 ohms.

find the frequency in cycles per second (angular frequency divided by 2 Pi) of the (gradually decaying) oscillatory current.

-------------

Do i need to use these values in the form ax'' + bx' + cx = f(t). If so what is f(t) meant to represent?

find the number of oscillations per e-folding of the gradual decay. (i.e. in the time that the amplitude reduces from a to a/e).

I'm not sure what this question means, how do the e-foldings relate to this?

Any help is appreciated. I'm fairly sure i could do this question if i knew the relationship. Am i missing the obvious?

Thanks. Pablod
