Question

In Rutherford scattering experiment, what will be. the correct angle for $\alpha$ scattering for an impact parameter $b=0$

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

Answer 1

Answer: (D)

Impact parameter $b\propto \cot \frac{\theta }{2}$ Here $b=0,$ hence, $\theta ={180}^o$
