Apoint of charge 4.9 μc is placed at the origin (x1 = 0) of a coordinate system, and another charge of -1.1 μc is placed on the x-axis at x2 = 0.28 m. a) where on the x-axis can a third charge be placed in meters so that the net force on it is zero?
b) what if both charges are positive; that is, what if the second charge is 1.9 μc?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
