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

  1. Attracted when x lies between A& B and are repelled when x lies between B&C.    
  2. Attracted when x lies between B and C and are repelled when x lies between A and B.    
  3. Attracted when they reach B.    
  4. Repelled when they reach B.    

The correct answer is: Attracted when x lies between B and C and are repelled when x lies between A and B.
