A positive point charge QQQ is located at a small distance x0x0x_0 from an extended non-conducting charged plate uniformly charged by a charge qqq (see figure). The charge QQQ begins to move
perpendicular to the plate, moving away from it. Which of the graphs
below correctly depicts the dependence of the force FFF of the Coulomb
interaction of a charge QQQ with a plate on the distance between
them?
