Question

A chemist in a galaxy far,far away performed the Millikan oil drop experiment and got the following results for the charges on various drops.
1.60 10-12 zirkombs 4.80 10-12 zirkombs
2.40 10-12 zirkombs 4.00 10-13 zirkombs
Use these data to calculate the probable charge of the electron in zirkombs.
_________ zirkombs
It is impossible to determine from this data the charge of an electron with certainty.Why is this?

Answer 1

最大公约数问题呀,可能的电子电荷量为4.00 10-13zirkombs(这个见鬼单位估计是杜撰的,不影响问题解决).
油滴带的带的电为基本电子电荷量的整数倍,就这四个数值来看,最大公约数为4.00 10-13zirkombs,实际上,电子电荷也可能是4.00 10-13zirkombs的一个因子.
