Electric Force Simulation
Forces on a central charge in square configuration
Central Charge
Corner Charges
Physics Explanation
This simulation demonstrates Coulomb's Law for a 1μC charge at the center of a square with four corner charges:
F = k·|q₁q₂|/r²
Where:
- F is the force between charges
- k is Coulomb's constant (9×10⁹ N·m²/C²)
- q₁, q₂ are the charges
- r is the distance between charges (7.07 cm from center to corner)
Key observations:
- Forces from equal charges at opposite corners cancel out
- Net force on the central charge is zero in this symmetric configuration
- Individual forces follow the direction of attraction/repulsion
Current net force: 0 N (all forces cancel out)
