A) 2h
B) \[\infty \]
C) \[\frac{5}{3}h\]
D) None of these
Correct Answer: D
Solution :
| [d] \[\frac{1}{2}mv{{'}^{2}}=\frac{1}{2}\frac{1}{2}m{{v}^{2}}\] |
| \[v'=\frac{v}{\sqrt{2}}\] \[v=eu\] |
| \[e=\frac{1}{\sqrt{2}}\] |
| \[H=\lambda \left( \frac{1+{{e}^{2}}}{1-{{e}^{2}}} \right)\] |
| \[=h\left( \frac{1+\frac{1}{2}}{1-\frac{1}{2}} \right)=3h\] |
