The system will be bound at points where total energy is negative. In the given curve at point A, B and C, the PE is more than KE

Q. The curves for potential energy $(U)$ and kinetic energy $(E_{k})$ of a two particle system are shown in figure. At what points the system will be bound?

Only at point D

Only at point A

At point D and A

At points A, B and C

The system will be bound at points where total energy is negative. In the given curve at point $A, B$ and $C$ , the $PE$ is more than $K E$
