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 5 × 10 4 m/s. The thrust on the rocket is Options: A . &nbsp2×103 N B . &nbsp5×104 N C . &nbsp2×106 N D . &nbsp2×109 N

Answer: Option C : C Thrust on the rocket F = u d m d t = 5 × 10 4 ( 40 ) = 2 × 10 6 N

Question

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

5 \times 10^{4}

m/s. The thrust on the rocket is

Options:

A . 2×103 N

B . 5×104 N

C . 2×106 N

D . 2×109 N

Answer: Option C
:
C
Thrust on the rocket

F = \frac{u d m}{d t} = 5 \times 10^{4} (40) = 2 \times 10^{6} N
