Detailed explanation-1: -The escape velocity from Earth is about 11.186 km/s at the surface. Escape velocity rises with the mass of the body and falls with the escaping object’s distance from its centre.
Detailed explanation-2: -escape velocity. noun. : the lowest velocity that a moving body (as a rocket) must have to escape from the field of gravity of the earth or of a heavenly body and move outward into space.
Detailed explanation-3: -GRAVITATION The escape speed of a projectile on earth’s surface is 11.2 km/s A body is projected out-YouTube.
Detailed explanation-4: -“The escape velocity of Earth is the speed at which a free object must travel to escape into space from a planet’s gravitational pull.” Earth’s escape velocity is 11.186 km/s. So, if a free body travels at this speed, it can break away from Earth’s gravity into outer space.
Detailed explanation-5: -Detailed Solution. The correct answer is option 2) i.e. 11.2 km/s. CONCEPT: Escape velocity(Ve): The minimum velocity that an object must attain to escape the gravitational pull of the Earth is called the escape velocity.
