The current velocity of a river grown in proportion to the distance from its bank and reaches the maximum value V_(0) in the middle. Near the banks the velocity is zero. A boat is moving along theriver in such a manner that it is always perpendicular to the current with respect to river and the speed of the boat in still water is U. Width of the river is C. Time taken by the boat to cross the river:

1.	The current velocity of a river grown in proportion to the distance from its bank and reaches the maximum value V_(0) in the middle. Near the banks the velocity is zero. A boat is moving along theriver in such a manner that it is always perpendicular to the current with respect to river and the speed of the boat in still water is U. Width of the river is C. Time taken by the boat to cross the river:
Answer» C/U `C//V_(0)` `C//sqrt(V_(0)^(2)+U^(2))` `C//sqrt(V_(0)^(2)-U^(2))` ANSWER :A
