Question

A plane intersects one nappe of a double-napped cone such that it is perpendicular to the vertical axis of the cone and it does not contain the vertex of the cone.
Which conic section is formed?
parabola
ellipse
circle
hyperbola

Answer 1

There is two possible conic section that can be formed when the plane intersects the vertical axis, a circle, and an ellipse. Cutting one nappe of double napped cone perpendicular to the vertical axis means the cut is straight across the cone making a right angle. The conic section formed would be a circle.
