- A factory is spray-painting large sheets of metal electrostatically. The sheets have dimensions of 2.4 m by 2.4 m and are charged with 0.82 mC. A 10 kg drum of paint is charged with -89 μCμC, and the spray nozzle produces uniform droplets of 2.4 g. Assume that all charge is distributed uniformly on the sheet and in the paint and no charge is lost during the spraying process. Determine the magnitude of acceleration the paint droplets feel due to the metal sheet. Give your answer in units of ms2ms2.One particle has a mass of 3.71 x 103 kg and a charge of +7.56 μC. A second particle has a mass of 7.17 x 103 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.177 m, the speed of the 3.71 x 103 kg-particle is 126 m/s. Find the initial separation between the particles.
