- A 38-g ball of copper has a net charge of 1 μC. What fraction of the copper's electrons have been removed? (Each neutral copper atom has 29 protons and 29 electrons, and copper has an atomic mass of 63.5 a.m.u.)A small metal sphere carrying a net charge of Q = -2.00 uC is held stationary by insulating supports. A second small metal sphere with a net charge of Q 2 = +7.80 uC and mass 1.50 g is is held 0.8 m away from the center of the first sphere. Assume the two spheres can be treated as point charges and that you can ignore gravity. If the second sphere is released, how fast will it be traveling when it is 0.6 m away from the center of the first sphere?Three point charges are located as shown in the figure. q1 =-9 x 10-12 [C) and d =5 [cm] 92 =1x 10-12 (C] and d; = 1 [cm] 93 =-4 x 10-2 (C) and dy = 7 [cm] 93 d3 a. n Jami the t 1 at the- 92 INA d, d, de electri nyutuae or tne eiectrio neld created by the charge g at the origin d E What ie thadie origin. e.t harge qs at the origin.
