A rocket has a mass of 100 kg . `90%` of this is fuel. It ejects fuel vapours at the rate of `1 kg//sec` with a velocity of 500 `m//sec` relative to the rocket. It is supposed that the rocket is outside the gravitational field. The initial upthrust on the rocket when it just starts moving upwards is
