Apositive charge q is placed at the origin. four other positive charges are placed on a circle in the x-y plane centered on q as shown. the top charge is located on the y axis and has a magnitude of 3q. the three bottom charges are symmetric about the y axis as shown and each has magnitude q.
1) which of the following statements best describes fx, the x component of the net force on the charge at the origin
fx > 0
fx = 0
fx < 0
3) for the collection of charges shown in the above problem, which of the following statements best describes fy, the y component of the net force on the charge at the origin
fy > 0
fy = 0
fy < 0
