Learning Goal: use Coulomb's law and superposition to analyze a two-dimensional system of point charges. In the initial configuration, what is the x component F3,net,x of the net force on 93? Three charges, 91 93 = = 6.5 C, 92 = -5.4 C, and 2.1 C, are located at the vertices of an equilateral triangle with side length d the figure. = 6.0 cm, as shown in F3,net,x = N In the initial configuration, what is the y component F3,net,y of the net force on q3? 93 d A 91 d x 92 F3,net,y= N After charge q4 is added (the second configuration), what is the x component F2,net,x of the net force on 92? F2,net,x = N Next, a charge 94 = 2.1 C is added, as shown in the figure. After charge 94 is added (the second configuration), what is the y component F2,net,y of the net force on q? y 93 d d 91 92 d. F2,net,y = N After charge 94 is added (the second configuration), what is the x component F1,net,x of the net force on q? d d F1,net,x = 94 N
