Explanation
System will be bound at points where total energy is negative. In the given curve at point A, B, and C the P.E. is more than K.E.
Gravitational P.E. = m x gravitational potential U = mv so the graph of U will be same as that of V for a spherical shell
The velocity of the spoon will be equal to the orbital velocity when dropped out of the space ship
6R from the surface of earth and 7R from the center
B.E.= –K.E.
And it this amount of energy(Ek) given to satellite it will escape into outer space
Because Earth rotation from west to east direction
