Atoms And Nuclei Question 70
Question: In Rutherford scattering experiment, what will be the correct angle for $ \alpha $ scattering for an impact parameter b = 0 [CBSE PMT 1994; JIPMER 2000]
Options:
A) $ 90^{o} $
B) $ 270^{o} $
C) $ 0^{o} $
D) $ 180^{o} $
Show Answer
Answer:
Correct Answer: D
Solution:
Impact parameter $ b\propto \cot \frac{\theta }{2} $ Here b = 0, hence $ \theta =180^{o} $
