Two spheres are made of conducting material. Sphere #2 has twice the radius of Sphere #1. What is the ratio of the capacitance of Sphere #2 to the capacitance of Sphere #1?
A. 1, since all conducting spheres have the same capacitance.
B. 2
C. 4
D. 8
E. A single sphere has no capacitance since a second concentric spherical shell is necessary to make a spherical capacitor. Thus, none of the answers above is correct.
