Hi, could someone offer some advice on the following problem:
=====
Q. Using Gauss' law, obtain expressions for the electric field and potential in the space between two thin, hollow, concentric conducting cylinders, of radii a and b, with the outer cylinder connected to earth
=====
I know that the E-field of the inner cylinder is E=Q/4piEoa^2 in the radial direction (if the cylinder has a charge of Q).
I also realize that if the outer cylinder was not connected to earth, it's just a capacitor.
However, I'm really confused as to what affect the earthing of the outer cylinder has on the electric field and potential in between the two cylinders!
Thanks
