A bob is attached to one end
of a string and other end
of which is fixed at peg A.
The bob is taken to a position
where string makes an angle
of 30° with the horizontal. On the circular path
of the bob in vertical plane there is peg B at a
symmetrical position with respect to the position
of bob as shown in the figure. If vc and va be the
minimum speeds in clockwise and anticlockwise
directions respectively, given to bob in order to
hit the peg B, then ratio vc : va is equal to
