A) \[\overline{PQRS}\]
B) \[2v\,\tan \phi \]
C) \[v\,\tan \phi \]
D) \[v\,\cot \phi \]
Correct Answer: C
Solution :
(c.)We can write \[\pi \sqrt{\frac{{{a}^{2}}}{2G\lambda }}\] Momentum of photon emitted \[2\pi \sqrt{\frac{{{a}^{2}}}{2G\lambda }}\] Recoil momentum of H-atom \[2\pi \sqrt{\frac{2{{a}^{2}}}{G\lambda }}\] \[\frac{\sqrt{2}}{\pi }\times \frac{1}{\sqrt{15LC}}\] \[\frac{1}{\sqrt{2}}\pi \times \frac{1}{\sqrt{15LC}}\] \[\frac{2\sqrt{2}}{\pi }\times \frac{1}{\sqrt{15LC}}\] \[\frac{\pi }{2}\times \frac{1}{\sqrt{15LC}}\]
