Chapter 2, Problem 20E

In an experiment similar to that described in Exercise 19, drop 1 carried a charge of $6.41\times {10}^{-15}$ C drop 2 had $\frac{1}{2}$ the charge of drop 1; drop 3 had twice the charge of drop 1, drop 4 had a charge $1.44\times {10}^{-15}$ C and drop 5 had $\frac{1}{3}$ the charge of drop 4. Are these data consistent with thevalue of the electronic charge given in the text? Could Millikan have inferred the charge on the electron from his particular series of data?
