In Millikan's experiment, oil droplets are introduced into the space between two flat
horizontal plates, 5.00 mm apart. The plate voltage is adjusted to exactly 780V SO
that the droplet is held stationary. The plate voltage is switched off and the selected
droplet is observed to fall a measured distance of 1.50 mm in 11.2 s. Given that the
density of the oil used is 900 kg mº, and the viscosity of air at laboratory temperature
is 1.80 x 10 Nm's, calculate
a) The mass, and b) The charge on the droplet (Assume g =9.8 ms?)
[Ans: (a) 5.14 x 10-15 kg, (b) 3.20 x 10-19 C]​
