Question

Chase and Kadri consider the following values, which are part of a set of experimental data for a Millikan oil-droplet experiment.

b = 1.48 ✕ 10⁻¹⁰ kg/s
d = 0.016 m
ρ_oil − ρ_air = 0.882 g/cm³
r = 3.0 ✕ 10⁻⁷ m
V = 5000 V

What is the terminal speed for a droplet of charge 3e?

To what value should the voltage be adjusted so that the droplet is suspended between the two plates?
