Two identical balls A and B. each of mass 2 kg and radius R, are suspended vertically from inextensible strings as shown in Fig. The third ball C of mass 1 kg and radius r=(sqrt(2)-1)R falls and hits A and B symmetrically with 10 m//s. Speed of both A and B just after the collision is 3 m//s. Impulse provided by each sting during collision is

Answer»

`6sqrt(2)NS`
`12NS`
`3sqrt(2)Ns`
`6Ns`

Solution :impulse provided by each STRING
`I_(1)=Isintheta=6Ns`
