Balance electric charges to prevent Tommy from slipping into icy water. You are presented with 4 particles, each with a charge value. Using the plus/minus scrollbar, you can change the value of the highlighted charge. Then press the play button to start the simulation. You must balance the forces on the right with the forces on the left to keep Tommy from falling into the icy depths!
