Answer:
According to Columb's force ,
Here Q₁ and Q₂ are the charge separated in r distance .
hence,
forces act between 1μC and 2μC ,
Similarly,
force act between 2μC and −3μC ,
Hence, graph between F and
r
2
1
,
will be straight line where line B has higher slope than line A as shown in figure above
