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 of electronic charge on the moon to electronic charge on the earth to be:

Solution & Step-by-step Explanation

The electronic charge (e) is a fundamental physical constant. It does not depend on the local acceleration due to gravity or the location in the universe. Whether the experiment is performed on Earth, the Moon, or anywhere else, the charge of an electron remains 1.6 \times 1 0^{- 19} C . Thus, the ratio is 1 .

Try it yourself before checking the explanation above.
