Q.	If the distance from the focus is 2 mm and the distance from the directrix is 0.5 mm then what is the name of the conic section?
A.	circle
B.	ellipse
C.	parabola
D.	hyperbola
Answer» D. hyperbola
Explanation: the eccentricity is defined as the ratio of the distance from the focus to the distance from the directrix. it is denoted as e. if the value of the eccentricity is greater than unity then the conic section is called as a hyperbola.
