a
4.3 x 10-2 N
b
4.3 N
c
4.3 x 106 N
d
4.2 x 1011 N

explanation would be highly appreciated!

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 ´ 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.
