Potential Energy: Two tiny particles having charges q1 = +56.0 nC and q2 = -46.0 nC are separated by 0.500 m and held in place, as shown in the figure. A third particle, having a charge of 54.0 nC is placed at the point A, which is 0.18 m to the left of q2. How much work is needed to move the third particle from point A to point B, which is 0.40 m to the left of q1. All the points in the figure lie on the same line. (k = 1/4??0 = 9.0 × 109 N ? m2/C2) 
Fill in the blank(s) with the appropriate word(s).
