1. The problem statement, all variables and given/known data A small conducting spherical Shell (#1) with inner radius a and outter radius b is concentric with a larger conducting spherical shell (#2) with inner radius C and outter radius d. The inner shell has a total charge (-3Q), and outter shell has a charge ( +5 Q). a) Use Gauss's law to find the electric field ( magnitude and direction) in terms of Q and r for i) r<a; ii) a<r<b; iii) b<r<c; iiii) c<r<d; b) determine the surface charge density on the inner and outer surfaces of both shells. 3. The attempt at a solution Electric field for i and iii is zero?
