Two beads of mass `2m` and `m`, connected by a rod of length `l` and of negligible mass are free to move in a smooth vertical circular wire frame of radius `l` as shown. Initially the system is held in horizontal position `(` Refer figure `)`

If the rod is replaced by a massless string of length `l` and the system is released when the string is horizontal then `:`

Two beads of mass 2m and m , connected by a rod of length l and of negligible mass are free to move in a smooth vertical circular wire frame of radius l as shown. Initially the system is held in horizontal position ( Refer figure ) The minimum velocity that should be given to the mass 2m in clockwise direction to make it vertical is :

Two beads of mass 2m and m , connected by a rod of length l and of negligible mass are free to move in a smooth vertical circular wire frame of radius l as shown. Initially the system is held in horizontal position ( Refer figure ) The velocity that should be given to mass 2m ( when rod is in horizontal position ) in counter - clockwise direction so that the rod just becomes vertical is :

Two small rings each of mass ‘m’ are connected to a block of same mass ‘m’ through inextensible light strings. Rings are constrained to move along a smooth horizontal rod. Initially system is held at rest (as shown in figure) with the strings just taut. Length of each string is ‘l’. The system is released from the position shown. Find the speed of the block (v) and speed of the rings (u) when the strings make an angle of theta=60^(@) with vertical. (Take g = 10 m//s^2 )
