A positively charged particle Q1 = +35 nC is held fixed at the origin. A second charge Q2 of mass m = 8.5 μg is floating a distance d = 35 cm above charge Q1. The net force on Q2 is equal to zero. You may assume this system is close to the surface of the Earth. Calculate the magnitude of Q2 in units of nanocoulombs.

A conducting sphere of radius r1 = 0.21 m has a total charge of Q = 1.6 μC. A second uncharged conducting sphere of radius r2 = 0.29 m is then connected to the first by a thin conducting wire. The spheres are separated by a very large distance compared to their size. What is the total charge on sphere two, Q2 in coulombs?
