The following observations were made for a series of five oil drops in an experiment similar to Millikan’s (see Figure

The following observations were made for a series of five oil drops in an experiment similar to Millikan’s (see Figure 2-8). Drop 1 carried a charge of   drops 2 and 3 each carried   the charge of drop 1; drop 4 carried   the charge of drop 1; drop 5 had a charge four times that of drop 1. Are these data consistent with the value of the electronic charge given in the text? Could Millikan have inferred the charge on the electron from this particular series of data? Explain.

Solutions

Expert Solution

Calculate the charge on each drop, express each in terms of 10-19 C. Finally, express each in terms of e = 1.6 × 10-19 C. The values are consistent with the charge that Millikan found for that of the electron, and he could have inferred the correct charge from these data, since they are all multiples of e.


Calculate drop charge in 10-19 C and in e (1.6 × 10-19 C); consistent with electron charge multiples.

In Millikan’s oil-drop experiment, one looks at a small oil drop held motionless between two plates. Take the voltage between the plates to be 2033 V, and the plate separation to be 2.00 cm. The oil drop (of density 0.81 g/cm3) has a diameter of 2.9 x 10-6m. Find the charge on the drop, in terms of electron units. You need to round your answer to the nearest integer.
