I am in general physics III (E&M) at Cal Poly and I have a midterm tomorrow... my professor didn't go over Gauss' Law too much, so I'm having issues with this problem that is on his review. I will write the question exactly as it appears on the sheet.
"You have a hollow conducting sphere with inner radius R1 and outer Radius R2. You place a point charge (-q) at the center of the sphere. What is the charge/unit area on the inner radius? On the outer radius?"
gauss's law
I used gauss's law and found the electric field of the charge, but I read through the textbook and through my notes and I can't seem to find anything on finding the "charge/unit area" on the hollow sphere. I understand how to use Gauss' law, but I just don't understand how I can find this charge...
Any help would be greatly appreciated
Thank!
