Question
An interaction between two molecules is treated as a one-dimensional simple spring. Which of the following statements are true about this motion if the molecules are initially compressed and then released and allowed to move freely?
There is a constant, non-zero force between the molecules and they will appear to vibrate/oscillate
There is a changing, non-zero force between the molecules and they will appear to vibrate/oscillate
There is a changing, non-zero force between the molecules and they will remain stationary
There is a constant, non-zero force between the molecules and they will remain stationary
Explanation / Answer
there is changing non zero force between the molecule and they will appear to vibrate..
spring force directly propotional to displacment..since displacment changes thereforce will change..
