Hi,
I have this question:
I am a little confused about the electric field of a very large sheet of something (insulator or conductor)
for a very large sheet, E = sigma_inclosed/2(epsilon_naught), but for a conductor, it is E = sigma_inclosed/epsilon_naught, that is, twice the first case. But I have a question here in my book that says:
A thin conducting plate 50 cm on a length lies in the x-y plane. If it is placed in an external electric field of 8*10^4C directed perpendicular to the plate, find;
1- The charge density of each face of the plate,
2- The total charge on each face.
The answers uses, E = sigma / 2(epsilon_naught) to find sigma,
Shouldn't he used the formula E = sigma_inclosed/epsilon_naught since it is a conducting plate?
