Question
A beam of fast moving alpha particles were directed towards a thin film of gold. The parts 
and 
of the transmitted and reflected beams corresponding to the incident parts 
and 
of the beam, are shown in the adjoining diagram. The number of alpha particles in
'/> will be minimum and in '/> maximum
'/> will be maximum and in '/> minimum
- '/> will be minimum and in '/> maximum
- '/> will be minimum and in '/> maximum
'/> will be minimum and in '/> maximum
'/> will be maximum and in '/> minimum
'/> will be minimum and in '/> maximum
'/> will be minimum and in '/> maximum
The correct answer is: will be maximum and in minimum
Because atom is hollow and whole mass of atom is concentrated in a small centre called nucleus
