Aplane intersects one nappe of a double-napped cone such that the plane is not perpendicular to the axis and is not parallel to the generating line.

which conic section is formed?

circle
ellipse
parabola
hyperbola

The conic section that is produced on such slicing is:

                                   Ellipse.      

Step-by-step explanation:

We know that when a slicing of a double nape cone is done such that the plane intersects one nape of a double-napped cone such that the plane is not perpendicular to the axis and is not parallel to the generating line then ellipse is formed.

( If the plane passes just one nape of a cone and is perpendicular to the axis then a circle is obtained.

and if a plane passes through just one nape of a cone and is parallel to the generating line than a parabola is obtained )
