The co-efficient of friction (both static and kinetic ) between the inclined plane and the block A of mass 1 kg is `1//sqrt(3)` whereas there is no friction between block B (1 kg ) and the inclined plane. The system starts from rest. When the system covers a distance s=30 m on the inclined plane, the cord between A and B is burnt. The velocity of A when it covers a further distance of 20 m on the inclined plane is

A

B

`sqrt(120) m//s`

C

`sqrt(150) m//s`

D
