Electromagnetic
force, and was a strong force in the universe's four fundamental forces
(gravity, electromagnetic force, strong nuclear force, weak nuclear
force), it's intensity after the strong nuclear force
Electrostatic force formula is: F = KQ1 * Q2 / R squared
In which Q1 and Q2 are two separate objects with power, r is the
distance between two objects, k is a constant.
When the atomic scale into time (0.1nm), will find all of the material
is composed of different atoms, while the atom is composed of different
atomic nuclei and electronic composition, with negatively charged
electrons and positively charged atomic nuclei (from protons and
neutrons have constituted) by the electromagnetic closely together.
However, the atomic scale, we must use to describe the quantized
electromagnetic field, this description method, that is, between the
role of the two particles as the exchange photon.
In fact, light is a kind of electromagnetic waves, quantum effects of
electromagnetic optical effect is. This description already in the 50's
are quite well developed, and is called quantum electrodynamics (quantum
electrodynamics, QED).
