Question

Identify which of the above shown graphs represents the force between two electrons Vs distance between them?

• A. Graph A
• B. Graph B
• C. Graph C
• D. Graph D
• E. Graph E

Answer 1

The correct option is A Graph A

The electric force between two electrons is given by ,

$F=\frac{1}{4\pi {\epsilon }_0}.\frac{e\times e}{r^2}$

where $r$ is the distance between two electrons ,

therefore , $F\propto 1/r^2$ , this relation is denoted by graph $A$ .
