Question

the magnitude of the potential energy per unit mass of the object at the surface of earth E .then the escape velocity of the object is ​

Answer 1

· It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. ... At this point the object ceases to accelerate and continues falling at a constant speed called the terminal velocity (also called settling velocity).
