At the height `320 m`, an aeroplane is moving with `100 m//s`. A bomb is droped from it so as to hit a target. At what horizontal distance from the target should the bomb be dropped

A

`200 m`

B

`400 m`

C

`600 m`

D

`800 m`

Text Solution

Verified by Experts

The correct Answer is:
D
`y = (g x^(2))/(2 u^(2)) rArr x = usqrt((2 y)/(g)) = 100sqrt((2 xx 320)/(10))`
`x = 800 m`
