In a rocket, fuel burns at the rate of (1 ~kg / s ). This fuel is ejected from the rocket with a velocity of (60 ~km / s ). The force exerted on the rocket by this is

Options

  1. A(60 ~N )
  2. B(600 ~N )
  3. C(6000 ~N )
  4. D(60000 ~N )

Correct answer

D. (60000 ~N )

Step-by-step solution

For a rocket, ( d m d t =1 ~kg / s ) Velocity of fuel ejected by rocket, (v=60 ~km / s =60000 ~m / s ) ( ) Force exerted on the rocket is given as (F=v d m d t =60000 1=60000 ~N )
