Question
In Rutherford's alpha-particle scattering experiment, only a few alpha particles rebound back because
Options
A.The size of gold nucleus is very small as compared to the size of gold atom.
B.Alpha particle and gold nucleus have equal charge.
C.The impact parameter is minimum for a few alpha particles.
D.A few alpha particles have very high kinetic energy.
Solution
Sol. [Key Concept: Back-scattering needs a very small nucleus (A), minimum impact parameter (C) and head-on collision (E).]
