An alpha nucleus of energy 1/2 mv2 bombards a heavy nuclear target of ...

Explanation:

Force experienced by the alpha nucleus:
- The alpha nucleus experiences a repulsive electrostatic force as it approaches the heavy nuclear target.
- This force causes the alpha nucleus to decelerate as it approaches the target.

Equating forces:
- At the point of closest approach, the electrostatic force must be equal to the centripetal force acting on the alpha nucleus.
- Equating these forces gives us an expression for the distance of closest approach.

Distance of closest approach:
- The distance of closest approach is inversely proportional to the kinetic energy of the alpha nucleus.
- Since kinetic energy is proportional to v^2, the distance of closest approach is proportional to 1/m.

Therefore, the distance of closest approach for the alpha nucleus is proportional to 1/m.
