Electric Potential of a Conducting Sphere
A hollow conducting sphere of radius R has a net charge Q. A point charge q is located at a distance 2R from the sphere’s center. Which of the following describes the change in the electric potential at the center of the sphere when the point charge is moved to infinity?
A
It decreases by a factor of Q/(Q + q/2)
B
It changes by a factor of qQ/(4πε₀R²)
C
It changes by a factor of Q/(4πε₀R)
D
It changes by a factor of q/(4πε₀R)
