Any charged object can exert this force upon other objects - both charged and uncharged objects. The Electric Field is non zero because you have two opposite charges and the field will start from the positive and end on the negative charge, continuously having a nonzero value. com The Coulomb's Law and Electric Field Package is a collection of models for electrostatics. Each module of the series covers a different topic and is further broken down into sub-topics. The rules for drawing electric field lines for any static configuration of charges are The lines begin on positive charges and terminate on negative charges. Electric Potential Energy • Moving an electric charge in an electric field requires or releases energy, U (Joules). That is done by specifying basic quantities and units, for instance – velocity, electric field and kinetic energy. pdf: 790.
