# calculating electric fields of charge distributions

Continuous charge distributions usually involve a single body which is either uniformly charged, or the charge density across the body varies as a function of the location of the point. This function is given in the problem statement and what is required is the expression of electric field at some point outside/inside the charge distribution.

Electric Fields In the previous unit on electricity and magnetism, we learned how an electric field E exists between two opposite charges q and –q at a distance r from each other. They attract each other, very much like gravity, with a force F given by .This force is called the Coulomb or the electric force, with units of Newtons like any other force.
