Pair Of Straight Lines Question 109
Question: The equation of the bisectors of the angles between the lines represented by $ x^{2}+2xy\cot \theta +y^{2}=0 $ , is
Options:
A) $ x^{2}-y^{2}=0 $
B) $ x^{2}-y^{2}=xy $
C) $ (x^{2}-y^{2})\cot \theta =2xy $
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
Equation of bisectors is given by $ \frac{x^{2}-y^{2}}{a-b}=\frac{xy}{h} $ or $ \frac{x^{2}-y^{2}}{0}=\frac{xy}{\cot \theta } $ or $ x^{2}-y^{2}=0 $ .
