If two point charges are separated by 0.015m and have charge values of 2.0 x 10^{-6} C and –4.0 x 10^{-6} C, respectively, what is the value of the mutual force between them? (k = 9 x 10^9 )

answer; nonlinear graph;

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.

like poles repel so keep pushing north to north and repels funny to see this

friction

explanation:

they us to move forward and backwards
