Two atoms interact with each other according to the following force `F` and potential energy `V` diagrams. What is their equilibrium separation?

Options

A. the seperation u which is equal to y
B. the seperation u which is equal to z
C. the separation w which is equal to y
D. the separation w which is equal to z

Answer

B

Explanation

For equilibrium `F=0and from F-x graph it is clear at x=4 f=0 from V-x graph`
it is clear that F`= (dv)/dx = 0at x=z`
