Question

A parallel plate air capacitor of capacitance 245pF has a charge of magnitude 0.148ìC on each plate. The plates are 0.328mm apart.
(a) What is the potential difference between the plates?
(b) What is the area of each plate?
(c) What is the electric field magnitude between the plates?
(d) What is the surface charge density on each plate?

Answer 1

Look up the appropriate formulas and apply them. That is how you will learn the subject. Don't give someone else your problems to do for you.

Answer 2

You are so dumb. This is supposed to be for people who need help.

Answer 3

uh, no. They're not "dumb". You're just mad that they called you out on cheating,which you like to call "asking for help"(help that you could just get from asking your teacher).
