The diagram shown the path of four `alpha`-particles of the same energy being scattered by the nucleus of an atom simutaneously. Which of these are/is not physically possible ?

Options

A. `3` and `4`
B. `2` and `3`
C. `1` and `4`
D. `4` only

Answer

D

Explanation

`alpha`particles cannot be attracted by the nuclues. As `A'` is transmitted beam appoximate undeviated hence particles should be maximum in this case `B'` is reflected beam as most of the `alpha` particles and get transmitted hence `alpha` particles should be minimum in this case.
