Question

When an α-particle of mass 'm' moving with velocity 'v' bombards on a heavy nucleus of charge 'Ze', its distance of closest approach from the nucleus depends on m as :

Answer 1

Distance of closest approach when an α-particle of mass m moving with velocity v is bombarded on a heavy nucleus of charge Ze, is given by  

Answer 2

Answer:

r0 ∝ 1/m

Explanation:

Mass of the particle = m (Given)

Velocity in the particle = v (Given)

Charge of the nucleus = Ze (Given)

The distance of the closest approach when an α-particle of mass m moving with velocity v is bombarded on a heavy nucleus of charge Ze, will be given by the equation -

r0 = Ze²/π∈mv²

Thus, r0 ∝ 1/m.

Therefore,  distance of closest approach from the nucleus depends on m as   r0 ∝ 1/m.
