A projectile passes two points `A` and `B` at same height after `2s` and `6s` of its projection. Horizontal separation between the points `A` and `B` is `120m`. The horizontal range is closest to [`g=10 m//s^(2)`] `

A

`180m`

B

`200m`

C

`240m`

D

`260m`

Text Solution

Verified by Experts

The correct Answer is:
3
Ans.(3)
Time of flight `T_(f)=2+6=8s`
For horizontal motion `A` to `B:Deltat=4s`
So `u_(x)=(120m)/(4s)=30m//s`
Range `=30xx8=240m`
