MCQ

The potential energy $U$ between two molecules as a function of the distance $r$ between them has been shown in the adjoining figure. The two molecules are:

A
Attracted when $r$ lies between $A$ and $B$ and repelled when $r$ lies between $B$ and $C.$
✓
Attracted when $r$ lies between $B$ and $C$ and repelled when $r$ lies between $A$ and $B.$
C
Attracted when they reach $B.$
D
Repelled when they reach $B.$

✓

Answer

Correct option: B.

Attracted when $r$ lies between $B$ and $C$ and repelled when $r$ lies between $A$ and $B.$
