Question

Solution

Correct option is  subtends a right angle at centre i.e. (0, 0)

∴ making homogeneous equation of hyperbola With the help of and putting coefficient of x2 + coefficient of y2 = 0 ‘p’ is also the length of perpendicular drawn from (0, 0) to the line then radius of circle SIMILAR QUESTIONS
