Small particulates can be removed from the emissions of a coal-fired power plant by a process known as electrostatic precipitator. the particles are given a small electric force on a spherical particle with a diameter of 1.0 micrometer is 2.0 x 10^-13 N. what is the speed of such a particle as it is drawn toward a plate? (the weight of the particle can be ignored since the electric force is much greater than the weight)
