Question

In the geiger-marsden experiment what percentage of the $\alpha$ particles were deflected by an angle more than $1^o$.

• A. $<0.15$
• B. $<15$
• C. $>99.85$
• D. $100$

Answer 1

The correct option is B $<15$

The Geiger-Marsden experiment, also called as the Rutherford's gold foil experiment were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where all of its positive charge and most of its mass are concentrated. They deduced this by measuring how an alpha particle beam is scattered when it strikes a thin metal foil. In this experiment they observed that only less than $15$% of th alpha partils
