question 13

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 0.60 m from the center is closest to

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