A hollow conducting spherical shell has radii of 0.80 m and 1.20 m, as shown in the figure. The sphere carries a net excess charge of -500 nC. A point charge of +300 nC is present at the center. (k = 1/47 80 = 8.99 x 10° N - m²/C) The radial component of the electric field at a point that is 0.60 m from the center is closest to A. zero. + 300 nC 1-1.2 m B. +7500 N/C. C.-7500 N/C. 0.80 m D. +5000 N/C. E. -5000 N/C.
