How did Robert Millikan's oil drop experiment change scientists' view of the atom?A.It showed that atoms could not be divided into smaller particles.B.It identified the location of the nucleus.C.It showed that atoms were found in different energy levels.D.It identified the charge on a single electron.SUBMITarrow_backPREVIOUS

Question 2 of 10What did Robert Millikan discover?A.He discovered the nucleus of the atom.B.He determined the radius of oil drops.C.He determined an electron's charge.D.He discovered that electrons orbited inside an atom.

In 1909 Robert Millikan carried out experiments to determine the magnitude of thecharge on an electron.His experiments involved the motion of small, electrically charged droplets of oilbetween two charged metal plates.Some students carried out a similar experiment in a school laboratory.(a) The terminal velocity v of an oil droplet was measured as it fell a known distancein air when the plates were uncharged. Stokes’ law was then used to determine theradius r of the oil droplet. Upthrust was ignored.(i) Show that r = 92ηvρgη = viscosity of airρ = density of oil
