Two ships, V and W, move with constant v...

Two ships, V and W, move with constant velocities `2 ms^(-1)` and `4 ms^(-1)` along two mutually perpendicular straight tracks toward the intersection point O. At the moment `t=0`, the ships V & W were located at distances `100 m` and `200 m` respectively from the point O.
The distance between them at time t is :-

A

`a^(2)y+bx^(2)=0`

B

`a^(2)y=bx^(2)`

C

`y=b/a^(2) x`

D

`ay^(2)=b^(2)x`

Text Solution

Verified by Experts

The correct Answer is:
B
`l=sqrt((100-2t)^(2)+(200-4t)^(2))`
