A) \[{{v}_{L}}/16\]
B) \[{{v}_{L}}/25\]
C) \[25\,\,{{v}_{L}}\]
D) \[16\,\,{{v}_{L}}\]
Correct Answer: B
Solution :
| [b] \[h{{v}_{L}}=13.6{{z}^{2}}\left( \frac{1}{1}-\frac{1}{\infty } \right)\] |
| \[hv'=13.6{{z}^{2}}\left( \frac{1}{25}-\frac{1}{\infty } \right)\] |
| \[\Rightarrow v'=\frac{{{v}_{L}}}{25}\] |
