The lines show the equipotential contours in the plane of three point charges, Q1, Q2, and Q3. The vaiues of the potentials are in IN as indicated for the +5, 0, and -5 kV contours. The positions of the charges are indicated by the dots. Am 1 2 H 4 5 l" The letters are on the equipotential contours. Calculate the work required to move a charge of -0.71x10-12C from i to b. -4.26*10^(-12)J The equipotential lines shown are separated by 1 $ {kV_u}. Work to move a charge is the increase in potential energy of the charge. The potential energy is the potential times the charge. Incorrect. Tries 6/6 Previous Tries Calculate the size of the electric field at g . -100.00 N/C The voltage decrease divided by the distance along which the voltage decreases the most. Submit Answer Incorrect. Tries 3/6 Previous Tries Calculate the size of the force on a charge of 6.40x10-19 C at k. 8.000*10^(-17)N First calculate the electric field in the same way as you did for the previous problem. Then, remember the relation between force and E-field. Submit Answer Incorrect. Tries 2/6 Previous Tries Calculate the size of Q3. The magnitudes of the three charges are in the exact ratios of 1 to 2 to 3. Submit Answer Tries 0/6
