A) \[\frac{3k}{5}\]
B) \[\frac{2k}{5}\]
C) \[k\]
D) \[\frac{5}{2k}\]
Correct Answer: D
Solution :
[d] |
\[{{\ell }_{A}}=\frac{2\ell }{5},{{\ell }_{B}}=\left( \frac{3\ell }{5} \right)\] |
\[K\ell ={{K}_{A}}{{\ell }_{B}}={{K}_{B}}{{\ell }_{B}}\] |
\[K\ell ={{K}_{A}}\left( \frac{2\ell }{5} \right)\] |
\[{{K}_{A}}=\frac{5K}{2}\] |
\[\Rightarrow \]\[{{K}_{B}}=\frac{5K}{3}.\] |
