Assertion (A): In Rutherford's alpha particle scattering experiment, the presence of only few alpha particles at angle of scattering \(\pi\) led him to the discovery of nucleus.
Reason \((R)\) : The size of nucleus is approximately \(10^{-5}\) times the size of an atom and therefore only few alpha particles are rebounded.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
(A) Both A and R are true and R is the correct explanation of A.
