Twо cоncentric sphericаl cоnducting shells hаve rаdii = 1.2 cm and = 13.2 cm as shown in the drawing. The shells have a finite thickness that is much less than either radius. The inner and outer shells carry net charges = 1.0 nC and = 3.3 nC respectively. What is the electric field strength at a distance 7.1 cm from the center of the sphere?
