Which postulate of Rutherford's theory is not derived from the results

1.	Which postulate of Rutherford's theory is not derived from the results of alpha-ray scattering experiment ? On what basis Rutherford's could assume that ?
Answer» Solution :The postulate that the electrons REVOLVE round the nucleus is not derived from the results of `alpha`-ray scattering experiment . The results of `alpha`-ray scattering GAVE the idea that entire positive charge is concentrated in a small part which is known as nucleus. In ORDER of counterbalance the NUCLEAR forces of attraction , the electrons revolve round the nucleus at very high SPEEDS.
