A 400 m wide river is flowing from west to east at velocity 3m/s. A boat starts from one bank and it crosses the river along the shortest path. When it reaches the middle of river, wind starts blowing horizontally along north-east at a velocity `sqrt(2)` m/s . Due to this, the direction of rowing of boat has to be changed for the boat to move along the shortest path. If the velocity of boat in still water with no wind blowing is 5 m/s, then choose the correct option(s).
