Problem
Six identical positive point charges +q are fixed at the vertices of a regular hexagon of side L. The charge at the topmost vertex is replaced by a charge of magnitude +2q. A positive test charge q0 is placed at the center of the hexagon.
Which statement correctly describes the direction of the net electric force on the test charge?
(a) The net force on the test charge is zero.
(b) It points directly toward the vertex immediately clockwise from the topmost vertex.
(c) It points directly away from the topmost vertex along the radial line connecting the center to that vertex.
(d) It points directly toward the topmost vertex along the radial line connecting the center to that vertex.
