Question

Two stationary electric charges ("A" and "B") initially exert a Coulomb Force F on each other. • Charge A is then tripled (e.g., from 2 µC to 6 μC). • The distance between charges A and B is also tripled. After all changes to the system have been made, what is the strength of the new Coulomb Force on each charge?

Step 1

The initial distance between them is $r$. The initial Coulomb force is given by Coulomb's law: $$F = k \frac{q_A q_B}{r^2}$$ where $k$ is Coulomb's constant. Show more…
