PHXI05:LAWS OF MOTION

363201 A right circular cone is fixed with its axis vertical and vertex down. A bead is in contact with its smooth inside surface and describes circular motion in a horizontal plane at the height of \(10\,cm\) above the vertex. Find its velocity in \({{m} / {s}}\). (Take \({\left.g=10 {~m} / {s}^{2}\right)}\)
