In the follow experiment, we will examine how the Coulomb force depends on
the charges. The purple and green atoms can be charged differently using
the buttons in the tables in the gray areas. The green atom is attached to
a spring, the other end of which is another atom that you can steer. Your
task is to drag the green atom into the yellow region.
