Suppose a scientist repeats the Millikan oil-drop
Chapter , Problem 2.87(choose chapter or problem)
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:
\(\begin{array}{c|c} \hline \text { Droplet } & \text { Calculated Charge (wa) } \\ \hline \text { A } & 3.84 \times 10^{-8} \\ \text { B } & 4.80 \times 10^{-8} \\ \text { C } & 2.88 \times 10^{-8} \\ \text { D } & 8.64 \times 10^{-8} \\ \hline \end{array}\)
(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?
(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?

Step by Step Solution
Step 1 of 4
(a)
Small size droplets are fll slowly. If all the droplets were of the same size so the one with smaller would fall into the apparatus more gradually.
