- Homework Statement
- There is a Physics textbook that states,
"Rutherford reasoned that:
"The core of the atom must be massive on atomic scale to deflect alpha particles through large angles."
- Relevant Equations
- F=kQ1Q2/R^2
The experimental observation of finding very few alpha particles scattered through large angles (>90) - I thought this would have inferred that the positive charge of the core of the atom (which we now come to know as the nuclei) must have been great in order greatly deflect alpha particles that came in its vicinity.
I came to this conclusion as I thought,
For a nuclei with smaller electric charge, it would result in the same alpha having a smaller angle of deflection , compared to that of a larger nulcei.
I don't understand how the size of the nulceus could effect how alpha particles are sctattered, and how the statement above is true .
