Question

If tangent to any members of family of hyperbolas  is not a normal to any member of family of circles , where μ is any real parameter, then θbelongs to  

Solution

Correct option is

All of these

 

The equation of the hyperbola is xy = c2, where . The equation of any tangent to it is . If it is normal to each member of the family of circles, it must pass through the centre of each circle i.e. (1, 1). 

This will have non-real roots, if
