Answer 2

Answer:

Option A

Explanation:

The locus developed by alpha particle depends solely on the impact parameter of the collision.

The impact parameter is actually is the distance at right angle of each alpha particle from the centre of the nucleus. In same trajectory all the particles will be carrying same kinetic energy so their movement will be on the impact.

The particles with less impact will experience bigger angle of scattering
