If a particulate, with a mass of 2.1 x 10-5 kg, acquires a charge of 3.2 uC, the electrical force on the particulate, due to the electric field is:

An electrostatic air cleaner is a device that removes polluting particulates, thus purifying air. As an example, contaminated air carrying a particulate, with a mass of 3.15 x 10^-9 kg, will first pass through a charging grid, removing an electron and charging the particulate with a +1 charge. These positive particulates are then removed by being attracted to the negative grid and remaining on the grid as the rest of the clean air passes through.
