A beam ofα-particle is incident on a gold foil. Corresponding to the incident beamsA,BandC, the emergent beamsA′,B′,andC′. The transmission and deflection ofα-particles through the foil take place such that

Options:

Answer:
A
Solution:

From figure, we can see thatBis reflected totally, so transmission ofBis minimum.

ButAis passing through foil with minimum deviation.

Therefore, transmission ofAis maximum.
