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
A) Only at point $D$
B) Only at point $A$
C) At point $D$ and $A$
D) At points $A,B$ and $C$
Explanation
(d) The 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.
