In the previous problem, How far from the point directly opposite to the starting point does the man reach the opposite bank
A. `1//6sqrt(3)km`
B. `2//3sqrt(3)km`
C. `4//3sqrt(3) km`
D. `5//sqrt(3) km`
A. `1//6sqrt(3)km`
B. `2//3sqrt(3)km`
C. `4//3sqrt(3) km`
D. `5//sqrt(3) km`
Correct Answer – A
`x=(2-3sin30^(@))t=1/(2) . 1/(3sqrt(3))`
`=1/(6sqrt(3)) km`
