A rocket is launched normal to the surface of the earth, away from the sun, along the line joining the sun and the earth. The sun is `3 xx 10^(5)` times heavier than the earth and is at a distance `2.5 xx 10^(4)` times larger than the radius of the earth. the escape velocity from earth's gravitational field is `u_(e) = 11.2 kms^(-1)`. The minmum initial velocity `(u_(e)) = 11.2 kms^(-1)`. the minimum initial velocity `(u_(s))` required for the rocket to be able to leave the sun-earth system is closest to (Ignore the rotation of the earth and the presence of any other planet
