The portion BC of tube is parallel to OO’ and its length is equal 0.4 m. At t=0, AB part of tube is filled with an ideal fluid. The end A of tube is open, the closed end C has a very small orifice. Find the maximum height reached by fluid relative to end C.

A circular ring of mass M and radius 'a' is placed in a gravity free space. A small particle of mass m placed on the axis of the ring at a distance sqrt(3)a from the center of the ring is released from rest. The velocity with which the particle passes through the center of the ring is
