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

Atoms

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 centre of the nucleus. For small impact parameter a particle close to the nucleus and suffers larger scattering.
