Using Coulomb's Law to Clean the Air y collector Collector 9 soot Modern smokestacks use devices called scrubbers to remove large amount of pollution in the form of small particles (soot). Scrubbers use a two steps process: electrons are first added to the soot particle, and an electric force then pulls the particle out of the smoke stream. Soot Consider a soot particle of mass msoot= 1.1 nanograms (1.1e-12 kg), particles which corresponds to a diameter of a few micrometers. Some number moving of electrons have been added to give the particle a total charge asoot- upward Suppose the collector has a total charge acollector 1.9e-06 C. If the separation between the collector and the soot particle is r = 0.15 m, Ground What is the magnitude of ¶soot (in units of C) so that the electric force exerted on the particle is equal to its weight = mg ?.
