The 1.29E-9 is wrong for capacitance...
AAAH. Fixed that and plugged in again.
YES I got 1.27E-13 for the magnitude of the plates. WHICH IS THE CORRECT ANSWER :D. OMG. It only took 4 hours xD.

I just wanted to thank you for being tenacious enough to stick with the help to the end. I'm so slow with new concepts ><. Thanks a lot, I really appreciate it.

no prob. :smile: everything takes time, experience, practice etc... just keep doing the problems, and it will become easier...
