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.
