A conducting sphere of radius r1 = 0.27 m has a total charge of Q = 2.6 μC. A second uncharged conducting sphere of radius r2 = 0.34 m connects to the first by a thin conducting wire. The spheres are separated by a very large distance compared to their size.   a. What is the total charge on sphere two Q2 after they are connected, in coulombs?  b. What is the surface charge density of the second sphere, σ2, after they are connected in coulombs per square meter?
