7. [-/8 Points] DETAILS SERCP11 15.8.P.053.MI. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Suppose the conducting spherical shell in the figure below carries a charge of 3.40 nC and that a charge of -1.00 nC is at the center of the sphere. If a = 1.80 m and b = 2.30 m, find the electric field at the following. b i (a) r = 1.50 m magnitude N/C direction ---Select--- V (b) r = 2.20 m magnitude N/C direction V ---Select--- radially inward (c) r = 2.5 radially outward magnitude The magnitude is zero. direction (d) What is the charge distribution on the sphere? inner surface nc outer surface nc Need Help?
