If a body is thrown from the Earth with a velocity of 11.2 km per second, then the body will never return to the Earth; Option [A]. This velocity exceeds the escape velocity of Earth, ensuring that the body will continue moving away from Earth indefinitely, unable to return due to the gravitational pull. The escape velocity of Earth, approximately 11.2 km/s at the Earth’s surface, represents the minimum speed required for an object to break free from Earth’s gravitational field and enter space. Once a body achieves or exceeds this velocity, it is no longer bound by Earth’s gravity and will not return. Therefore, option A, “Never return to the Earth,” is the correct answer. This principle is fundamental to understanding space travel and celestial mechanics, as it governs the conditions under which objects can escape from planetary bodies and explore the cosmos. In summary, a body thrown from Earth with a velocity of 11.2 km/s will not return, as it has achieved escape velocity and will continue its journey away from Earth indefinitely.
