Vedclass · Answer

(A) The electronic charge is a fundamental physical constant and is an intrinsic property of an electron. It does not depend on the gravitational field or the location where the measurement is performed. Millikan's oil drop experiment determines the value of the elementary charge $e$,which is approximately $1.602 	imes 10^{-19} \ C$. Since the charge of an electron remains constant regardless of the acceleration due to gravity ($g_E$ or $g_M$),the ratio of the electronic charge on the moon to the electronic charge on the earth is $1$.

If $g_E$ and $g_M$ are the accelerations due to gravity on the surfaces of the earth and the moon respectively and if Millikan's oil drop experiment could be performed on the two surfaces,one will find the ratio (electronic charge on the moon / electronic charge on the earth) to be
