How do you find the distance to the closest approach?

How do you find the distance to the closest approach?

How does the distance of closest approach change?

How does the distance of closest approach charge? Solution : As the distance of closest approach is inversely proportional to the kinetic energy of the incident `alpha-("particle")`, so the distance of. closest approach is halved when the kinetic energy of `alpha-("particle")` is doubled.

The impact parameter is the perpendicular distance to the closest approach if the projectile were undeflected. For the special case of alpha scattering from a nucleus of atomic number Z, the relationship is more convenient in the form to the right.

What is the distance of closest approach How does its measurement lead to nuclear size?

By shooting alpha particles of kinetic energy 5.5 MeV, the point of closest approach was estimated to be about 4×10-14m. Since the repulsive force acting here is Coulomb repulsion, there is no contact. This means that the size of the nucleus is smaller than 4×10-14m.
