Impact Parameter Rutherford Scattering

Statement-1: Impact parameter for scattering of alpha particles by 180^(@) is zero. Statement-2 : Zero impact parameter means alpha particle tends to hit the centre of the nucleus

In Rutherford scattering experiment, wha will be the ratio of impact parameter for scattering angles theta_(1)=90^(@) and theta_(2)=120^(@)

In Rutherford scattering experiment, wha will be the ratio of impact parameter for scattering angles theta_(1)=90^(@) and theta_(2)=120^(@)

What is impact parameters for scattering by 180^@ ?

What is the impact parameter for scattering of alpha -particle by 180^(@) ?

For scattering by an inverse-square field (such as that produced by a charged nucleus in Rutherford's model) the relation between impact parameter b and the scattering angle theta is given by, the scattering angle for b=0 is
