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

A

the separation `u` which is equal to `y`

B

the separation `u` which is equal to `z`

C

the separation `w` which is equal to `y`

D

the separation `w` which is equal to `z`

Text Solution

Verified by Experts

The correct Answer is:
B
At equuilibrium separation, `F=0` and `V` is minimum.
