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)

Options

A. `2.30xx10^(-15)`
B. `1.38xx10^(-14)`
C. `6.90xx10^(-15)`
D. `1.15xx10^(-15)`

Answer

A, B, C

Explanation

`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.
