From the value of one charge, and the sum from the first step, get the other charge.
From the force and the values of the two charges, get the separation R using Coulomb's law.

Coulomb's law states that the electric force between two charges is given by the equation:
F = (k * |q1 * q2|) / r^2
where F is the electric force between the charges, k is the electrostatic constant (k = 8.99 x 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
Given that the electric force between the charges is 2.76 Newtons and one of the charges is -14.9 micro-Coulombs (-14.9 x 10^-6 C), we can rearrange the equation to solve for the distance:
r = √((k * |q1 * q2|) / F)
Plugging in the values we have:
r = √((8.99 x 10^9 N m^2/C^2 * |(14.9 x 10^-6 C) * (14.9 x 10^-6 C)|) / (2.76 N))
Now we can calculate the distance by evaluating this expression.
