Atoms And Nuclei Question 297
Question: In Rutherford scattering experiment, what will be the correct angle for a-scattering for an impact parameter, b=0?
Options:
A) $ 90{}^\circ $
B) $ 270{}^\circ $
C) $ 0{}^\circ $
D) $ 180{}^\circ $
Show Answer
Answer:
Correct Answer: D
Solution:
- $ b=\frac{Ze^{2}\cot ( \frac{\theta }{2} )}{4\pi {\varepsilon_{0}}k_{i}}=0\Rightarrow \cot ( \frac{\theta }{2} )=0 $
$ \Rightarrow \frac{\theta }{2}=90{}^\circ \text{ or }\theta =180{}^\circ $
