Two point charges, +3 C and -6 C, are separated by 2.0 m. They are NOT free to move. What is the magnitude of the electrostatic (Coulomb) force between the charges? Set up the needed equation(s), but do not attempt to obtain a numerical result. (Leave your answer as a function of k.) What is the net electric field at the point halfway between the two charges? Set up the needed equation(s), but do not attempt to obtain a numerical result. (Leave your answer as a function of k.) What is the net electric potential at the point halfway between the two charges? Set up the needed equation(s), but do not attempt to obtain a numerical result. (Leave your answer as a function of k.)
