Answer:
The conic section that is produced on such slicing is:
Ellipse.
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 )
