Homework Statement
A parallel-plate capacitor has a plate area of .3m^2 and a plate separation of .1mm. If the charge on ech plate has a magnitude of 5*10^-6C then the force exerted by one plate on the other has what magnitude
Homework Equations
Q=E Ԑ A
F=qE
The Attempt at a Solution
so to solve for E i used the first equation: 5*10^-6C=E*(10^-11)(.2) and got E=1.67*10^6 V/m
First i want to make sure that i am moving in the right direction and also do i use 5*10^-6C as my q in the second equation?
