1.	Which of the following observations was not correct during Rutherford's scattering experiment?
Answer» Most of the `alpha`-PARTICLES passed through the gold foil undeflected. A small fraction of the `alpha`-particles was DEFLECTED by small angles. A large number of the `alpha`-particles were BOUNCED BACK. A very few `alpha`-particles ( ~1 in 20,000) were bounced back. Solution :Only a few `alpha`-particles (1 in 20,000) bounced back.
