A bob of mass m suspended by a string of length is given a minimum velocity required to complete a full circle in the vertical plane At the highest point it collides elastically with another bob of mass m suspended by a string of length 12 which is initially at rest Both the strings are mass less and inextensible If the second bob after collision acquires the minimum speed required to complete a full circle in the vertical plane the ratio 1 12 is
