Plot a graph showing the variation of coulomb force (F) versus `((1)/(r^(2)))`, where r is the distance between the two charges of each pair of charges:
`(1mu C,2mu C) and (2muC-3muC)`. Interpet the graphs obtained.

Explanation

To solve the problem of plotting the graph showing the variation of Coulomb force (F) versus \( \frac{1}{r^2} \) for the given pairs of charges, we will follow these steps:

### Step 1: Understand Coulomb's Law
Coulomb's Law states that the force \( F \) between two point charges \( q_1 \) and \( q_2 \) separated by a distance \( r \) is given by:
\[ F = \frac{1}{4 \pi \epsilon_0} \frac{q_1 q_2}{r^2} \]
Where:
