Superposition of Forces
The superposition principle (superposition property) states that for all linear forces the total force is a vector sum of individual forces.
Spherical Distribution of Charge
The charge distribution around a molecule is spherical in nature, and creates a sort of electrostatic "cloud" around the molecule.
Solving Problems with Vectors and Coulomb's Law
Coulomb's Law, which calculates the electric force between charged particles, can be written in vector notation as
