Given `|V_br| = 4 m//s =` magnitude of velocity of boatman with respect to river, `v_r= 2 m//s` in the directior shown. Boatman wants to reach from point A to point B. At what angle `theta` should he row his boat ?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Net velocity is along AB or at `45^@` if,

`4 cos theta=4 sin theta+2`
Solving this equation we get,
`theta~~24.3^@`
