1. Homework Statement
I need to find the total charge inside the small metal sphere, inside the big metal sphere as well as outside the big metal sphere.
What confuses me is the electric field vector. Since it's only poiting in one direction it can't originate from a single charge, or a group of charges. What could produce such a field?
[/B]
I know I'm supposed to use Gauss' law.
For the small sphere. The amount and magnitude of electric field lines entering and leaving is the same. Which indicates that there is no charge inside the small sphere. As for the big sphere, inside and outside I honestly have no clue how to proceed. You should multiply the electric field with the perpedicular area. However if there is only one electrif field line, what area? Once again, so greateful for any idées/nods in the right direction!
