Electrostatic force obeys a linear principle: when multiple charges exert forces on a test charge, the total force is simply the vector sum of all individual forces, as if each source charge acted alone. This means forces don't interfere with or shield each other—they add independently. Recognizing superposition lets you break complex multi-charge problems into manageable pieces, calculating one pair-wise force at a time before combining them.
