Question

There are two thin, neutral, silver plates that are parallel, and are separated by a distance that is large compared to their thickness, but insignificant with respect to the square root of the area of any of them -One of the plates has an area four times greater than the other area than the other (A = 4a).

-A small charge + q is deposited on the minor plate.

-Given the induction principle, we know that a quantity q of negative charges inside the large plate will be attracted to and will approach the positive charge q deposited on the smaller plate, attracted by the positive charge

. ----------------------------------------

1)TRUE OR FALSE (Why or why not):

"We can then say that the surface charge density (σ) of the large plate will be -q / A."

2) How would you calculate the electric field in the middle of the plates, and at a distance d (equal to the separation of the plates) to the right of the smaller plate?
