A Hollow Conducting Spherical Shell Has Radii of 0

question 17

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. (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C) The radial component of the electric field at a point that is 1.50 m from the center is closest to

• A) +1200 N/C.
• B) +2000 N/C.
• C) -800 N/C.
• D) -1600 N/C.
• E) -2000 N/C.
