question 24

Multiple Choice

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.

• A) zero.
• B) +5000 N/C.
• C) +7500 N/C.
• D) -5000 N/C.
• E) -7500 N/C.
