Question

Which experiment is responsible for finding out the charge on an electron? (A) Millikans oil drop experiment (B) Cathode ray discharge tube experiment (C) Rutherford’s α-rays scattering experiment (D) Photoelectric experiment

Tardigrade Admin · Accepted Answer

The value (magnitude) of electron charge was determined by Millikan's oil drop experiment. Cathode ray discharge tube experiment gave the sign of electron charge Rutherford's experiment gave the presence of electrons around the dense nucleus Photoelectric experiment explained the production of electricity from light irradiation on the metal surface
