A river is flowing due east with a speed...

A river is flowing due east with a speed more than the maximum speed with which a person can swim in still water. He intends to cross the river by shortest possible path. Which of the following is correct?

A

He should start normal to the river bank.

B

He should start in such a way that, he moves normal to the bank, relative to the bank

C

He should starts in a particular (calculated) direction making an obtuse angle with the direction of water current

D

The man cannot cross the river, in that way.

Text Solution

Verified by Experts

The correct Answer is:
D

In this case As `V_(w)gtV_(sw)`
As `sin theta` can not be greater than 1, he can not reach directly opposite bank in this way.
