A hollow conducting sphere has radii of 0.80 m and 1.20 m. The sphere carries a charge of -500 nc. A point charge of + 300nC is present at the center.
In the figure, the radial component of the electric field at a point which is 1.50 m from the center is closest to:
a. +2000 N/C

b. -2000 N/C

c. +1200 N/C

d. -800 N/C

e. -1600 N/C
