Question

4.
When a gold sheet is bombarded by a beam of alpha particles, only a few of
them get deflected whereas most go straight undeflected.This is because:
1) The force of attraction exerted on the alpha particles by the oppositely
charged electrons is not sufficient,
2) A nucleus has a much smaller volume than that of an atom.
3) The force of repulsion acting on the fast-moving alpha particles is very small
4) The neutrons in the nucleus do not have any effect on the alpha particles.​

Answer 1

Answer:

hope it works

Explanation:

Due to small size of nucleus as compare to atom most of the α particle goes straight, some got very little deflection & 1 in 20,000 rebounds back.
