Solution

The correct option is D $60000 N$
Overall momentum of the system is conserved.
Therefore, change in momentum of the rocket will be equal to that of the fuel.
Change in momentum of the fuel will be
$Δ m v = 60000$
Hence, change in momentum of the rocket will also be:
$△ P = 60000$
Thrust force $F = \frac{△ p}{△ t}$
$F = 60000 N$
