Gravitation

Question

To project a body of mass … from earth's surface to infinity, the required kinetic energy is (assume, the radius of earth is … acceleration due to gravity on the surface of earth):

Accepted Answer

Option C. The kinetic energy required to project a body of mass … from the Earth's surface to infinity, also known as the escape kinetic energy, can be calculated using the concept of gravitational potential energy. The escape velocity … is the velocity a body must have to escape the gravitational field of the Earth without any further propulsion. The formula for escape velocity is:
