In Millikan's oil drop experiment, the charge on a oil drop was found due to an experimental error, to be `8.88 xx 10^(-18)C`. Why can't such a quantity of charge be present on the oil drop ? Explain. (Charge on an electron is `1.6 xx 10^(-19)C`)

Text Solution

Verified by Experts

Is it possible for a body to have charge less than `1.6 xx 10^(-19)C` as it is the charge of a fundamental particle? Is `8.88 xx 10^(-18)C` and integral multiple of `1.602 xx 10^(-19)C`?
