1.	The ring R in the arrangement shown can slide along a smooth fixed, horizontal rod XY. It is attached to the block B by a light string. The block is released from rest, with the string horizontal. Then which of the following are true.
Answer» ONE point in the STRING will have only vertical motion `R` and `B` will always have momentum of same magnitude When the string becomes vertical, the speeds of `R` and `B` will be inversely proportional to their masses `R` will lose contact with the rod at some point Answer :A::C
