Rutherford Scattering Trajectory

[says]

Homework Statement

Carbon scatters on a proton. What is the limit of the angle of scattering?

I'm not really sure where to start this question. I know it has something to do with Rutherford Scattering and impact parameter.

The Attempt at a Solution

Can the scattering angle be as large as 180°? If not, why not?

 

[says]

The scattering angle will be small, because the target (proton) is much smaller than carbon.
