AI Generated Solution

To solve the question "What happens to the kinetic energy of the particle at the distance of closest approach?", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Concept of Distance of Closest Approach**: - The distance of closest approach refers to the minimum distance between the alpha particle and the nucleus of an atom (e.g., a gold atom) during a scattering experiment. At this point, the alpha particle is closest to the nucleus before it is repelled. **Hint**: Remember that this distance is significant in understanding the interaction between charged particles. ...
