Match List-I with List-II:
| List-I | List-II | ||
|---|---|---|---|
| A | J.J. Thomson | I | Oil drop method for charge |
| B | R.A. Millikan | II | Discovery of neutron |
| C | James Chadwick | III | Measurement of \( e/m_e \) ratio |
| D | Ernest Rutherford | IV | Nuclear model of atom |
Choose the correct answer from the options given below:
Correct answer · Option 4
A-(III), B-(I), C-(II), D-(IV)
Explanation
Thomson measured \( e/m_e \), Millikan measured charge via oil drop, Chadwick discovered neutrons, and Rutherford proposed the nuclear model.
