Question

In Rutherford's scattering experiment , if impact parameter is zero then angle of scatting for $\alpha$ particleis

• A. ${90}^o$
• B. ${270}^o$
• C. ${180}^o$
• D. $0^o$

Answer 1

The correct option is C ${180}^o$

Since we know that in a bean all alpha particles have same kinetic energy the scattering of particles depend on impact parameter. Since impact parameter is zero particles closer to the nuclear experience large of scattering so the correct answer is ${180}^0$.
