In an oil drop experiment, the following charges (in arbitrary units) were found on a series of oil droplets : 2.30×10^–15, 6.90 × 10^–15, 1.38 × 10^–14, 5.75 × 10^–15, 3.45 × 10^–15, 1.96 × 10^–14. The experimental value suggests not possible magnitude of the charge on the electron is (in the same arbitrary unit)

Detailed Solution

1.15×10^–15, which is the largest number which divides all the given experimental values of the charge.
The smallest charge noted is 2.3×10^–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
