Suppose a scientist repeats the Millikan oil-drop experiment but reports the charges on the drops using an unusual (and imaginary) unit called the warmomb (wa). The scientist obtains the following data for four of the drops:
(a) If all the droplets were the same size, which would fall most slowly through the apparatus? (b) From these data, what is the best choice for the charge of the electron in warmombs?
Droplet Calculated Charge (wa)
A..............................3.84 × 10-8
B..............................4.80 × 10-8
C..............................2.88 × 10-8
D..............................8.64 × 10-8
(c) Based on your answer to part (b), how many electrons are there on each of the droplets?
(d) What is the conversion factor between warmombs and coulombs?
