4 cm 3 cm 2 cm → 0< 13. a. How much work would it take to move a -12 µC point charge from point A to point B? [6.89 J] 9, = 5µC 92 = -7µC b. How much work would it take to move an electron from point B to point A, in eV? [5.74x10° eV – be sure to show work for this.] 40 cm 30° 14. Three charges start out infinitely far away from this triangle, and infinitely far away from each other. What is the total amount of work needed to move each of the following charges from infinity to the numbered spots on the triangle? (qı to point 1, etc)? qı=-1.5 mC, q2= +3.8 mC, q3= -2.1 mC [9.6x10ª J] 40 cm 30° 70 cm
