Two concentric conducting spherical shells produce a radially outward electric field of magnitude 49,000 N/C at a point 4.10 m from the center of the shells. The outer surface of the larger shell has a radius of 3.75 m
If the inner shell contains an excess charge of -5.30 ?C, find the amount of charge on the outer surface of the larger shell. (k = 1/4??0 = 8.99 × 109 N ? m2/C2)
91.6 µC
