State Coulomb's law.Show graphically the variation of (a) F and 1/r² and (b) F and r. |

Answer» think , your question is -------Plot a graph showing the variation of coulomb force (F) versus (1/r²),where r is the distance between the two charges of each pair of charges:(1μC,2μC) and (2μC,-3μC).Interpret the graphs obtained. solution :- according to Columbus force , \bold{F\propto\frac{Q_1Q_2}{r^2}}F∝ r 2
Q 1
Q 2
Here Q₁ and Q₂ are the charge separated in r distance . HENCE, force , F_AF A
act between 1μC and 2μC , \bold{F_A\propto\frac{2}{r^2}}F A
∝ r 2
2
Similarly,force F_BF B
act between 2μC and -3μC , \bold{F_B\propto\frac{-6}{r^2}}F B
∝ r 2
−6
Now, here you can see that, |F_B|\ \textgreater \ |F_A|∣F B
∣ > ∣F A
∣ Hence, graph between F and 1/r² , will be straight line where line B has HIGHER slope than line A as shown in figure |
