A) \[{{K}_{A}}<{{K}_{B}}\]
B) \[{{K}_{A}}>{{K}_{B}}\]
C) \[{{K}_{A}}={{K}_{B}}\]
D) \[{{K}_{A}}=2{{K}_{B}}\]
Correct Answer: A
Solution :
We know that, \[K=\frac{{{L}^{2}}}{2I}\] Given, \[{{L}_{A}}={{L}_{B}}\] and \[{{I}_{A}}>{{I}_{B}}\] \[\therefore \] \[\frac{{{K}_{A}}}{{{K}_{B}}}=\frac{{{I}_{B}}}{{{I}_{A}}}<1\] \[\Rightarrow \] \[{{K}_{A}}<{{K}_{B}}\]You need to login to perform this action.
