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?
A Van de Graaff generator has a 0.045 mC charge on its conducting spherical terminal.
a.What is the magnitude of the electric field 2.7 m from the center of the terminal of the Van de Graaff generator? Since that distance is greater than the radius of the terminal, the field is the same as that due to the same charge concentrated at the center. Give your answer in newtons per coulomb.
b. At this distance, what is the magnitude of the force that the field exerts on a 2.1 μC point charge on the Van de Graaff generator's belt? Give your answer in newtons.
