The mass and radius of the sun are 1.99 × 1030 kg and R=6.96 × 108 m. The escape velocity of rocket from the sun is =......km/s
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 3×105 times heavier than the Earth and is at a distance 2.5×104 times larger than the radius of the Earth. The escape velocity from Earth's gravitational field is ve=11.2 km/s. The minimum initial velocity (vs) 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)
