is there any kaplan -esqe tutoring service for physics? i don't really want another student tutoring me... i want somebody who is a professional tutor. electromagnetic waves are kicking my ass... and i don't think i'm going to get any better at it from re-reading what i've already re-read.
or, if somebody wants to explain how to do this, that would work as well:
A circular-plate capacitor has a radius R= 30 mm and a plate separation of 5.2 mm. A sinusoidal potential difference with a maximum value of 162 Volts and a frequency of 60.0 Hz is applied between the plates. Find the maximum value of the induced magnetic field (in units of pT = 10^-12 Tesla) at a radius R, the capacitor radius.
