-8 μC 4 cm +4uC +5MC +2 cm Three charges are arranged as shown in the figure. How much work was necessary to move the middle charge from infinity into this arrangement (with the other two charges already fixed in place)? W = J Submit
1) Find Xpositive. Xpositive Q₁ A charge Q1 = -2.1 x 10-9 C is at the origin and a charge Q2 = 9.2 x 10-9 C is on the x-axis at x = 3 m. The potential is zero at two locations on the x-axis, Xpositive and negative. 2) Find Xnegative. Xnegative = m Submit Help Q₂ m Submit Help
