A) \[1<e<\frac{2}{\sqrt{3}}\]
B) \[e=\frac{2}{\sqrt{3}}\]
C) \[e=\frac{\sqrt{3}}{2}\]
D) \[e>\frac{2}{\sqrt{3}}\]
Correct Answer: B
Solution :
Let the hyperbola be \[\frac{{{x}^{2}}}{{{a}^{2}}}-\frac{{{y}^{2}}}{{{b}^{2}}}=1\] and any double ordinate \[PO\] be\[(a\sec \theta ,\,\,b\tan \theta ),\,\,(a\sec \theta ,\,\,-b\tan \theta )\] and \[O\] is centre\[(0,\,\,0)\]. \[\Delta OPQ\]being equilateral.You need to login to perform this action.
