A pair of perpendicular straight lines passes through the origin and also through the point of intersection of the curve with . The set containing the value of is
Explanation for correct option:
Step1. Given the equation of curve and line.
Given curve is
Given line is
The line will intersect the circle at points.
We make a homogeneous equation by using .
Since this is a perpendicular pair of straight lines,
Step2. To find the set of values of :
Coefficient of coefficient of
So,
Hence, the correct option is A
