Question

In an oil drop experiment , the following charge (in orbitary units) were found on a series of all droplets `2.30 xx 10^(-15),6.90 xx 10^(-15) xx 1.38 xx 10^(-14),5.75 xx 10^(-15), 3.45 xx 10^(-15),,1.96 xx 10^(-15),`.Calculate the magnitude of the charge on the electron

Answer 1

`1.15 xx 10^(-15)` is the largest number that divides all the listed charge every .The smaller of the cahrge listed is `2.30 xx 10^(-15)` but this cahrge does not divide into all the other an even number of times `2.30 xx 10^(-15)` must represent tthe charge of two electron
