Answer:
r = 14.13 m
Step-by-step explanation:
Given that,
Charge 1 = +0.0129 C
Charge 2 = -0.00707 C
The force between charges, F = 4110 N
We need to find the distance between charges. Let the distance be r. The force between two charges is given by :
![F=(kq_1q_2)/(r^2)\\\\4110=(9* 10^9* 0.0129* 0.00707)/(r^2)\\\\r=\sqrt{(9* 10^9* 0.0129* 0.00707)/(4110)} \\\\r=14.13\ m](https://img.qammunity.org/2022/formulas/physics/high-school/1973stq464592vd4o8hru7n1jh55xspczi.png)
So, the distance between charges is equal to 14.13 m.
