The figure shows the equipotential contours due to three point charges The labels on the contours are in Volts 3 y axis m O 15 312 1 476 5 828 0 221 71 118 1 828 0 663 6 87 3 20 L 15 10 5 0 x axis m a 357 9 83 0 0 0 53 7 5 15 3 38 9 10 15 The electric field at e is directed normal to the 221 7 V contour and away from the 3121 V contour A charge released from rest on one of these contours will not move along the contour Two of charges are positive and one is negative 118 1 J of work is done to move a charge of 1 Coulomb from d to c along the contour
