I have a question?

Two spherical conductors of radii r1 and r2 are separated by a distance much greater than the radius of either sphere. The spheres are connected by a conducting wire as shown in the figure. The charges on the spheres in equilibrium are q1 and q2, respectively, and they are uniformly charged. Find the ratio of the magnitudes of the electric fields at the surfaces of the spheres.

What if initially a charge 1.7 C is put on shell #1 with radius 4.8 m, then a far away shell #2 (initially neutral) with radius 9.6 m is connected to shell #1 by a long conducting wire.

(a) What is the final charge on shell #1?

Q = _ C 

Use the conditions that the total charge is Q and that the potential is the same on both spheres to find how the charge Q is distributed between the two spheres. Your response differs from the correct answer by more than 10%. Double check your calculations.

(b) What is the final charge on shell #2?

Q = _ C 

Use the conditions that the total charge is Q and that the potential is the same on both spheres to find how the charge Q is distributed between the two spheres. Your response differs from the correct answer by more than 10%. Double check your calculations.
