In millikan’s experiment, the oil droplets acquire one or more negative charges by combining with the negative charges that are produced from the ionization of air by x rays. by measuring the charges on the oil droplets, he calculated the charge on a single electron as −1.60×10−19 c. the charge on any negatively charged oil droplet is always a whole-number multiple of the fundamental charge of a single electron. if millikan was measuring the charge on an oil droplet with 4 negatively charged electrons on it, what charge would he have measured on the droplet?
