A) 0
B) 1
C) 2
D) 4
Correct Answer: A
Solution :
A and B are \[(\sqrt{5},1)\] and\[(-\sqrt{5},-1).\] Let C be \[(2sec\theta ,2tan\theta ).\] \[O(0,0)\]is the mid point of AB. Slope of \[OC=\sin \theta \]and slope of \[AB=\frac{1}{\sqrt{5}}\] Since \[OC\bot AB.\] \[\sin \theta =-\sqrt{5}\]which is impossible.You need to login to perform this action.
