Electrostatic Forces of Two Charges on a Third
- Lenore Horner
Drag charges to move them around. Drag black dots on horiztonal lines (sliders) to change charge values. Drag forceScale slider to rescale all forces so they are a "nice" size relative to the screen. In addition to the menu item, you should be able to scroll around the picture by shift-dragging and to zoom in and out by shift-rightclick-dragdown and shift-rightclick-dragup. I have my laptop set so 2-finger-tap is right-click so for me these are shift-twofingertap-drag.
