+Q

placed on it. Which of the following is the correct relationship for the electric potential at the points labeled

\mathrm{A}, \mathrm{B}

, and C ? Point A is at the center of the sphere, point B is at the surface of the shell, a distance R from point A , and point C is a distance R from point B outside the sphere. As

r

goes to infinity,

V=0

. (A)

\mathrm{V}_{\mathrm{C}}<\mathrm{V}_{\mathrm{B}}<\mathrm{V}_{\mathrm{A}}

(B)

\mathrm{V}_{\mathrm{A}}<\mathrm{V}_{\mathrm{B}}<\mathrm{V}_{\mathrm{C}}

(C)

V_{C}=V_{B}=V_{A}

(D)

\mathrm{V}_{\mathrm{C}}<\mathrm{V}_{\mathrm{B}}=\mathrm{V}_{\mathrm{A}}
