MCQ

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

A
$90^{\circ}$
B
$270^{\circ}$
C
$0^{\circ}$
✓
$180^{\circ}$

✓

Answer

Correct option: D.

$180^{\circ}$

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