Question

A hollow metal sphere has inner radius a and out radius b. The hollow sphere has charge +6Q. A -2Q charge sits at the center of the hollow sphere. a) Determine the electrical field in the regions of r equal or smaller than a, a < r < b, and r bigger or equal than b. b) How much charge is on the inside surface of the hollow sphere? On the exterior surface? c) Draw a graph of Electric Field vs r where r goes from zero to infinite. Also, show why Electric field is zero inside the conductor. THANK YOU!!

Explanation / Answer

rb 3/4-1 - since it will have to cancel out the +Q in the center3 - to create a +2Q charge on the sphere as a result of the-Q on the inner surfacehope this helps!
