Homework Statement
Two parallel plates have charges Q and -Q. When the space between the plates is devoid of matter, the electric field is 2.7E5 V/m. When the space is filled with a certain dielectric, the field is reduced to 1.3E5 V/m.
What is the dielectric constant of the dielectric?
I got this answer as 2.07692, which was correct.
If Q = 8 nC, what is the area of the plates?
I tried plugging the numbers into the formulas below, but I'm not getting the right answer...Am I missing a piece of relevant information?
What is the total induced charge on either face of the dielectric?
This will be easier once I figure out the second question.
Homework Equations
E=E(not)/kappa
V=Ed
C=Q/V
C=epsilon(not)*kappa*Area/distance
The Attempt at a Solution
I got the first answer, and the second I could not get.
