**The Electric force**** 02/14/16**

A most useful riveting concept found in the study of electromagnetism is the electric force. The electric force is defined as the at-a-distance interaction between two charge particles, described by the equation Felec=q1*q24**0*r2 . As one can discern, the Force is proportional to the strength of the two charges, a constant, and the square of the distance between them. This equation is kindred in nature to the Universal Gravitation equation, substituting mass for electric charge and changing around the constants, a most intriguing symmetry found in physics. However, there is one glaring incongruity in the fact that the electrically charged particles can be either positive or negative, while mass can only exist in a positive value.
