# 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

Where:

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.

Calculating the Attractive Force when the Net Force between Two Atoms and the Repulsive Force is Given.

FA = FN – FR

Where:

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

Let’s solve an example;
Find the attractive force when the net force between two atoms is 10 and the repulsive force is 6.

This implies that;

FN = Net Force between Two Atoms = 10
FR = Repulsive Force = 6

FA = FN – FR
FA = 10 – 6
FA = 4

Therefore, the attractive force is 4 N.

Calculating the Repulsive Force when the Net Force between Two Atoms and the Attractive Force is Given.

FR = FN – FA

Where:

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

Given an example;
Find the repulsive force when the net force between two atoms is 20 and the attractive force is 12.

This implies that;

FN = Net Force between Two Atoms = 20
FA = Attractive Force = 12

FR = FN – FA
FR = 20 – 12
FR = 8

Therefore, the repulsive force is 8 N.
