Question

A ray emanating from the point (5,0) is incident on the hyperbola 9 x squared minus 16 y squared equals 144 at the point P with abscissa 8. The equation of the reflected ray after first reflection is (P lies in first quadrant)

  1. 3 square root of 3 x plus 13 y plus 15 square root of 3 equals 0
  2. 3 square root of 3 x minus 13 y plus 15 square root of 3 equals 0
  3. 3 square root of 3 x plus 13 y minus 15 square root of 3 equals 0
  4. none of these

The correct answer is: 3 square root of 3 x minus 13 y plus 15 square root of 3 equals 0
