The angle between tangents to the parabola `y^2=4ax` at the points where it intersects with teine `x-y-a = 0` is `(a> 0)`A. `pi//3`B. `pi//4`C. `pi//6`D. `pi//2` |

Answer» Correct Answer - D (4) The coordinates of the focus of the parabola `y^(2)=4ax` are (a,0). the line y-x-a=0 passes through this point. Therefore, it is a focal chord of the parabola. Hence, the tangent intersects at right angle. |
