The Law of Gravity

Newton's law of gravitation says that the force between two massive objects is proportional to, so there's a proportionality constant. Coulomb's law is pretty much exactly the same except instead of the mass of the object, we have into the equation we put the charge of the objects. So essentially we've got a double negative here instead of a triple negative before. That leaves us with a positive sign, so the overall force is positive, and therefore the charges attract each other. The electric field is not a scalar field, it's actually a vector field which is slightly different but also very important.
