In a reproduction of the Millikan oil-drop experiment, astudent obtains the following values for the charges onnine different oil droplets.6.563 × 10-19 C 13.13 × 10-19 C 19.71 × 10-19 C 8.204 × 10-19 C 16.48 × 10-19 C 22.89 × 10-19 C 11.50 × 10-19 C 18.08 × 10-19 C 26.18 × 10-19 C (a) Based on these data alone, what is your best estimateof the number of electrons on each of the above droplets? (Hint: Begin by considering differences in charges between adjacent data points, and see into what groups these are categorized.)(b) Based on these data alone, what is your best estimate of the charge on the electron?(c) Is it conceivable that the actual charge is half the charge you calculated in (b)? What evidence would help you decide one way or the other?
In a reproduction of the Millikan oil-drop experiment, a
student obtains the following values for the charges on
nine different oil droplets.
6.563 × 10-19 C 13.13 × 10-19 C 19.71 × 10-19 C
8.204 × 10-19 C 16.48 × 10-19 C 22.89 × 10-19 C
11.50 × 10-19 C 18.08 × 10-19 C 26.18 × 10-19 C
(a) Based on these data alone, what is your best estimate
of the number of electrons on each of the above droplets? (Hint: Begin by considering differences in charges between adjacent data points, and see into what groups these are categorized.)
(b) Based on these data alone, what is your best estimate of the charge on the electron?
(c) Is it conceivable that the actual charge is half the charge you calculated in
(b)? What evidence would help you decide one way or the other?
