In a rocket of mass 1000 kg fuel is consumed at a rate of 40 kg/s . The velocity of the gases ejected from the rocket is `5xx10^(4)m//s`. The thrust on the rocket is

Options

A. `2 xx 10^3 N`
B. `2 xx 10^4 N`
C. `2 xx 10^6 N`
D. `2 xx 10^8 N`

Answer

C

Explanation

Thrust ,` F=u ((dm)/(dt )) = 5 xx 10^4 xx 40 =2 xx 10^6 N`
