In Milikan's experiment, static electrons charge on the oil drops has been obtained by shining X-rays. If the static electric charge on the oil drop is `-1.282xx10^(-18)C`, calculate the number of electrons present on it.

Text Solution

Verified by Experts

Electrons present = `(-1.282 xx 10^(-18)C)/(-1.6022 xx 10^(-19)C) = 8`
