<h3>What is the free body diagram?</h3>Free-body diagrams are utilized to display the relative direction and strength of all forces that are being applied to an item in a certain scenario. A unique illustration of the geometric diagrams that were covered in a previous lesson is the free-body diagram. We will make use of these graphics throughout the entire study of physics.
A university student is carrying a backpack. One strap is hanging the rucksack immobile from one shoulder.
The weight of the backpack is balanced by the shoulder of the student.
The free-body diagram is attached below.

Answer :
New force becomes, F' = 1.83 N
Explanation:
Let two point charges exert a force of 7.35 N force on each other. The electric force between two charges is given by :
are charges
r is the distance between charges if the distance between them is increased by a factor of 2, r' = 2r
New force is given by :
F' = 1.83 N
So, the new force between charges will be 1.83 N. Therefore, this is the required solution.
