Consider five point particles as shown in the figure below. The magnitude of the charge on each particle is the same, but some are negative and others are positive as

indicated in the figure. Also, the distance between the particle at the origin and each of the other four particles is the same. What is the direction of the electric force on the particle at the origin? A)negative y direction B)positive z direction C)positive x direction D)positive y direction E)negative x direction F)negative z direction
