प्रश्न
Why is Coulomb's law alone not enough when several charges are around a given charge?
पर्याय
It gives the force between two charges, but the net force must account for several charges.
It applies only to charges in a medium other than vacuum.
It applies only when all charges have the same sign.
It gives only the direction and not the magnitude of a force.

उत्तर
Coulomb's law gives the mutual force between a pair of charges. With several charges present, the net force requires combining the force from each of the other charges.
