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. $0^{o}$
• D. $180^{o}$

Answer 1

Answer: (D)

$180^{o}$

Answer 2

Impact parameter $b \propto \cot\frac{\theta}{2}$

Here b = 0, hence $\theta = 180^{o}$
