Sphere 1 with radius r1 has positive charge q sphere 2 with, Ask an Expert

Academics

Sphere 1 with radius R1 has positive charge q. Sphere 2 with radius 9.00R1 is far from sphere 1 and initially uncharged. The separated spheres are then connected with a wire thin enough to retain only negligible charge.

(a) What is the ratio V1/V2 of the final potentials of the spheres?

(b) What fraction of q ends up on sphere 1?

(d) What is the ratio s1/s2 of the surface charge densities of the spheres?
