A) \[\frac{\pi }{3}\]
B) \[\frac{2\pi }{3}\]
C) \[\frac{\pi }{4}\]
D) \[\frac{\pi }{2}\]
Correct Answer: D
Solution :
End points are \[(a,\,\,\pm \,2a).\] \[\therefore \]Tangents are , \[\pm 2ay=2a(x+a)\]or \[m=\pm \frac{2a}{2a}=\pm 1\] Hence angle between them is \[\frac{\pi }{2}\].You need to login to perform this action.
