an electric charge creates an electric field around itself with a certain directional vector
by Coulomb's law,
The magnitude of the electrostatic force between two point electric charges is directly proportional to the product of the magnitudes of each charge and inversely proportional to the square of the distance between the charges.
And hence, 2 charges, if of the same sign, repel each other.
And when 2 charges of different signs come close, they attract each other. When put near but not too close, the electric field that they create as individual charges are distorted. When even closer together, the resultant electric field is quite different from the electric field created by each charge.
pretty fun to apply physics to love. How different can people be when they are in love and when they are as individuals? How differently do they behave as a couple and when alone? There's no right or wrong, just interesting social phenomenons.
no more time to indulge in such random musings, got to in office early to deliberate on diagrams and models. again it's interesting, on how games like sims are modeled after real life. like how resources are limited, and how you need to gain 'points' or scores under certain parameters e.g. cooking, technical yadah yadah, before you can progress up any particular career.
such games are modeled after tjhe real world, yet in the real world, we somehow don't know how things work, but in games we do.
