How to Calculate and Solve for Net Force between Two Atoms | Crystal Structures

The image above represents net force between two atoms.

To compute for net force between two atoms, two essential parameters are needed and these parameters are Attractive Force (FAand Repulsive Force (FR).

The formula for calculating net force between two atoms:

FN = FA + FR


FN = Net Force between Two Atoms
FA = Attractive Force
FR = Repulsive Force

Given an example;
Find the net force between two atoms when the attractive force is 15 and the repulsive force is 3.

This implies that;

FA = Attractive Force = 15
FR = Repulsive Force = 3

FN = FA + FR
FN = 15 + 3
FN = 18

Therefore, the net force between two atoms is 18 N.
