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^(@)

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

for scattering by an inverse square law 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 b=(Ze^2 cot theta//2)/(4pi in_0(1/2mv^2)) (a) What is the scattering angle for b=0? (b) for given impact parameter, b, does the angle of deflection increase or decrease with increase in energy? (c) What is the impact parameter at which the scattering angle is 90^@ for Z=79 and initial energy=10MeV? (d) Why is it that the mass of the nucleus does not enter the formula above, but its charge does? (e) for a given energy of the projectile, does the scattering angle increase or decrease with decrease in impact parameter?

The impact parameter at which the scattering angle is 90^(0) , z=79 and initial energy 10MeV is

The significant result deduced from the Rutherford's scattering experiment is that

What is the impact parameter at which the scattering angle is 10^(@) for Z = 79 and initial energy of the alpha -particle is 5MeV ?
