AI Generated Solution

To calculate the ratio of electric to gravitational force between two electrons, we will use Coulomb's law for the electric force and Newton's law of gravitation for the gravitational force. Let's break down the solution step by step. ### Step 1: Write down the formulas for electric and gravitational forces. 1. **Electric Force (Coulomb's Law)**: \[ F_E = k \frac{q_1 q_2}{r^2} \] ...
