A man wishes to cross a river flowing with velocity `u` swims at an angle `theta` with the river flow.If the man swims with speed `v`and if the width of the river is `d`, then the drift travelled by him is

A

`(u+v cos theta)(d)/(v sin theta)`

B

`(u-cos theta)(d)/(v sin theta)`

C

`(u-v cos theta)(d)/(v cos theta)`

D

`(u+v cos theta)(d)/(v cos theta)`

Text Solution

Verified by Experts

The correct Answer is:
a

`x=(u+v cos theta)t=(u+u cos theta)(d)/(v sin theta)`
