A) 112/min, 12.5/min
B) 100/min, 200/min
C) 50/min, 12.5/min
D) 117/min, 25/min
Correct Answer: A
Solution :
\[N\propto \left[ \frac{1}{{{\sin }^{4}}\theta /2} \right]\] Þ \[{{N}_{1}}=7\times \frac{1}{{{(\sin {{30}^{o}})}^{4}}}=112\] and \[{{N}_{2}}=7\times \frac{1}{{{(\sin {{60}^{o}})}^{4}}}=12.5\].You need to login to perform this action.
