The maximum range of a gun on horizontal...

The maximum range of a gun on horizontal terrain is 1km. If `g = 10 ms^(-2)`, what must be the muzzle velocity of the shell ?

A

200 m/s

B

400 m/s

C

100 m/s

D

50 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`R_("max") = u^(2)/g rArr 16 xx 10^(3) = u^(2)/10`
`rArr u = 400 m//s`
