JEE Math Practice Question
Let x = 4 be a directrix to an ellipse whose centre is at the origin and its eccentricity is $${1 \over 2}$$. If P(1, $$\beta $$), $$\beta $$ > 0 is a point on this ellipse, then the equation of the normal to it at P is :
- A.4x – 3y = 2
- B.8x – 2y = 5
- C.7x – 4y = 1
- D.4x – 2y = 1
