Two small spheres carry electric charges of equal magnitudes. There are equally spaced points (a , b , and c) which lie along the same line. a b c − + What is the direction of the net electric field at each point due to these charges?

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
