charge density q is
Coulombs/kg. Assume the electric field in the scrubber is produced by two parallel square plates of width L = 1.0 m separated by a distance of d = 0.010 m, and carrying a charge Q each.
1. What must be the value of the electric field between the plates, so that force on the soot particle is equal to the weight of the particle?
(Hint: A real scrubber would use a collection of many pairs of such plates in parallel. )
2. What charge Q on the scrubber’s plates is required to produce the above electric field?
