The surface of the drum of a laser printer is negatively charged,except in certain "print black" regions, such as letterforms, thathave been discharged by a laser beam. Negatively charged inkparticles carrying a charge of 5.0 mC cling to the "printblack" areas but are repelled by an electric field elsewhere on the drum whose strength at the surface equals 120,000 N/C. What is the magnitude of the repelling force felt by these particles?
