He determined the ratio of mass to charge for electrons.

Explanation:

Robert Millikan's famous oil drop experiment allowed him to determine the charge of an electron. By observing the motion of charged oil droplets in an electric field, Millikan was able to measure the charge on individual electrons and calculate their mass-to-charge ratio. This groundbreaking work advanced our understanding of the fundamental properties of electrons and helped validate the concept of quantized electric charge.
