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 `3xx10^5` times heavier than the Earth and is at a distance `2.5xx10^4` times larger than the radius of the Earth. The escape velocity from Earth’s gravitational field is `v_e=11.2 km s^(-1)`. The minimum initial velocity `(v_s)` required for the rocket to be able to leave the Sun-Earth system is closest to
(Ignore the rotation and revolution of the Earth and the presence of any other planet)
