Question
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: (1 μC, 2 μC) and (2 μC, − 3 μC). Interpret the graphs obtained.

Solution
I am answering it as Graph between F vs `1/r^2`for (1μC, 2μC)
For (2μC − 3μC)
Interpretation
Graphs show that `F ∝ 1/r^2`
-
Slope gives a constant value and depends only on nature of charges and medium.
-
Ist graph is for repulsive force in Ist quadrant and IInd graph is for attractive force in IVth quadrant i.e., F > 0 and F < 0 respectively.
