Vedclass · Answer

(B) According to Rutherford's $\alpha$-particle scattering experiment,the following observations were made:$(i)$ Most of the $\alpha$-particles passed through the gold foil undeflected,corresponding to path $A-A^{\prime}$.(ii) $A$ small fraction of $\alpha$-particles were scattered by small angles,corresponding to path $C-C^{\prime}$.(iii) $A$ very small fraction of $\alpha$-particles were scattered by large angles (or reflected back),corresponding to path $B-B^{\prime}$.Since the number of particles scattered decreases as the scattering angle increases,the number of particles $n$ follows the order $n_{A^{\prime}} > n_{C^{\prime}} > n_{B^{\prime}}$.Therefore,the number of $\alpha$-particles is maximum in $A^{\prime}$ and minimum in $B^{\prime}$.

$A$ beam of fast-moving alpha particles was directed towards a thin gold foil. The parts $A, B$,and $C$ of the incident beam and their corresponding transmitted or reflected parts $A^{\prime}, B^{\prime}$,and $C^{\prime}$ are shown in the adjoining diagram. The number of alpha particles in:
