Millikan Oil Drop Lab You are viewing the drop that is in Equilibrium Measure the radius of the drop The oil density is 900 kg/m^3 Calculate the Volume and Mass of the drop Calculate the Fg on the drop Set Fe = Fg 600 500 400 300 200 100 100 200 300 400 500 600 The capacitor plates are 3.0 mm apart The AV between plates is 13.4 V Calculate the Electric Field between the plates. Find the charge on the oil drop. scale in nm Return to Main

Use the zoomed in image to measure the radius of the droplet.  Take note that the units on the scale are in nanometers (nm), .  Record the droplet radius and the ‘ΔV between plates’ values 

need to in m units please show how to measure radius and where to fint the number for between plates
