An aeroplane flying 490 m above the ground level at 100 m/s, releases a block. How far on the ground will it strike-

A

0.1 km

B

1 km

C

2 km

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B

`X=v sqrt((2h)/(g))`
`X = 100 sqrt((2 xx 490)/(9.8))= 10^(3)" m"=1" km"`
