Coulomb force vs separation
Slide two charges apart and watch the force weaken.
What to notice
Doubling the distance quarters the force — an inverse-square law.
Key relation
F = kq₁q₂/r²
Try this
Halve the separation and see the force quadruple.
What you can change
- Charge 1: 1 to 10 µC
- Charge 2: 1 to 10 µC
- Separation: 5 to 60 cm
