Twо cоncentric sphericаl cоnducting shells hаve rаdii = 4.6 cm and = 11.9 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 = 2.7 nC and = 4.4 nC respectively. What is the electric field strength at a distance 17.0 cm from the center of the sphere?
