[b]Two charge particle Coulomb's Law & Graphing Simulation:[/b][br][br]Instructions: Use “Move” cursor to change locations of charges q_L and Q_L and observe change in electric force on charge q, F_Eq as a function of separation.[br]Magnitude of electric force versus position will appear on graph insert. To see inverse square relationship on graph insert, select point and turn on trace. [br]Use the “Refresh” command to remove the trace.[br]Magnitude of electric force will also change as a function of changing the size of small charge q or large charge Q using sliders. [br]Direction of force flips depending on sign of product of two charge: likes repel, opposites attract.[br]To see Newton's Third Law “Action-Action” pair change slider to 1.[br]Note this is NOT a misspelling, reaction implies a time delay - See if you can observe a delay in the force on the other charge![br][br]James Vesenka, University of New England 2015
