1.	In an oil drop experiment, the following charges (in arbitrary units) were found on a series of oil droplets : 2.30 xx 10^(-15) , 6.90 xx 10^(-15) , 1.38 xx 10^(-14) , 5.75xx10^(-15) , 3.45 xx10^(-15) , 1.96 xx 10^(-14) . The experimental value suggests not possible magnitude of the charge on the electron is in the same arbitrary unit)
Answer» `2.30xx10^(-15)` `1.38xx10^(-14)` `6.90xx10^(-15)` `1.15xx10^(-15)` Solution :`1.15 xx 10^(-15)` , which is the largest NUMBER which divides all the given experimental VALUES of the charge. The smallest charge noted is `2.3 xx 10^(-15)` , but this charge doesn.t seem as unit charge, doesn.t DIVIDE others into EVEN number of times. Actually , it REPRESENTS the charges of 2 electrons.
