Question

In Geiger-Marsden scattering experiment, the trajectory traced by an $\alpha -$ depends on

A

Number of collision

B

Number of scattered $\alpha -$ particles

C

Impact parameter

D

None of these

Answer

Impact parameter

Explanation

Solution

Trajectory of $\alpha -$ particle depends on impact parameter which is the perpendicular distance of the initial velocity vector of the $\alpha$ particle from the center of the nucleus for small impact parameter $\alpha$ particle close to the nucleus and suffers larger scattering.
