Q1
A body of mass ' m ' connected to a massless and unstretchable string goes in vertical circle of radius ' R ' under gravity g . The other end of the string is fixed at the center of circle. If velocity at top of circular path is \(n\sqrt{gR}\), where, \(n⩾1\), then ratio of kinetic energy of the body at bottom to that at top of the circle is
