An interactive simulation with two point charges. Controls: q₁ (-10 to +10 μC), q₂ (-10 to +10 μC), separation r (1-50 cm). Force calculated and displayed: F = kq₁q₂/r² (k=9×10⁹). Force arrows show direction (attractive or repulsive). A bar chart shows force magnitude. Students investigate: (1) Doub
