Question

An object launched with escape velocity is intended to have just enough energy to reach an infinite distance from Earth. What is its final total energy (kinetic + potential) at this infinite distance?

विकल्प

• Infinite

• Zero

• Equal to its kinetic energy

• Negative

Answer 1

Zero

Explanation:

At an infinite distance, both the gravitational potential energy and the final kinetic energy become zero, making the total final energy zero.
