A bead of mass moves along a fixed vertical circle of radius 'R'. The bead is attached to
highest point of the circle with a light spring of spring constant 'k. If 9 shown in figure is
taken as generalised co-ordinate what is lagrangian of the system [Natural length of
spring is 2R and gravitation potential energy is taken to be zero at the centre o fcircle].
