1. The problem statement, all variables and given/known data A hollow metal sphere has inner radius a and outer radius b. The hollow sphere has charge +2Q. A point charge +Q sits at the center of the hollow sphere. Determine the magnitude of the electric field in the region r < a. Determine the magnitude of the electric field in the region a < r < b. Determine the magnitude of the electric field in the region r >b. Solve in Q/(pi*Eo*r^2) units 2. Relevant equations Net Flux=Q/Eo Net Flux= integral(E*dA) 3. The attempt at a solution Not really sure how to approach. I figured it was fairly straight forward since the units you solve for pretty much get rid of the calculation. I thought it would be 1 when r<a 2 for when a<r<b and 0 for r>b but none of them work and Ive used numbers around that. So I guess I need some explaining on this because I can't figure out any of the problems similar to this when it comes to net flux. So if anyone can also provide some explanation to what I am doing here that would be appreciated.
