A river of width w is flowing with a uniform velocity V . A bpat starts moving from point P also with velocity V relative to the river . The direction of resultant velocity is always perpendicular to the line joining boat and the fixed point R .point Q is on the opposite side of the river P , Q and R are in a staight line .If PQ=QR= w find (a) the trajectory of the boat (b) the drifting of the boat and (c) the time taken by the boat to cross the river.
