Question

# If the normal at the point P() to the ellipse intersects it again at the point Q(2) then cos =

- –2/3
- 2/3
- – 6/7
- 6/7

Hint:

### In this question, we have to find the value of cos, if the normal at the point P() to the ellipse intersects it again at the point Q(2). First we will find the value of a and b using the equation given and then find the equation of normal passing through first point. Later substituting the second point in the first equation and simplify it to get the required value.

## The correct answer is: –2/3
