A swimmer wants to cross a river which is flowing at a speed ' \(v\) '. If the swimmer can swim in still water at speed ' \(\mathrm{V}\) ', the direction he should swim to cross the river in least time is
- A Along the flow of river
- B Opposite to the flow of river
- C Perpendicular to the flow of river
- D \(45^{\circ}\) to the flow of river
Answer & Solution
Correct Answer
(C) Perpendicular to the flow of river
Step-by-step Solution
Detailed explanation
If the swimmer wants to cross the river in least time than he must swim perpendicular to the flow of the river.
