Question

If the velocity of alpha particles increases when the angle of deviation ____________________ . a) increases b) decreases c) remains same d) cannot be predicted

Answer 1

Answer:

It would decrease

Explanation:

The Impact Parameter is the perpendicular distance of the velocity vector of the alpha particle from the centre of the nucleus, when the particle is far away from the nucleus of the atom. Thus, angle of deviation for the alpha particles becomes smaller as the value of impact parameter increases.
