Question

A swimmer wants to cross a river from point A to point B . Line AB makes an angle of 30 &#176; with the flow of the river. The magnitude of the velocity of the swimmer is the same as that of the river. The angle &#952; with the line A B should be _______ &#176; , so that the swimmer reaches point B .

Correct answer: 0

Both velocity vectors are of same magnitude therefore resultant would pass exactly midway through them &#952; = 30 &#176;
