23. The diagram below shows a door viewed from above. Much to their parent's annoyance, two kids are fighting over opening/closing the door - do not do this at home! (Note that the door does not have a latch exerting any force on it) The diagram below shows the force that child A is exerting on the door: of magnitude F in the south direction, a distance of L/3 from the hinge. N wefe W E S F hinge L/3 L Child B decides to exert a force on the edge of the door, as far as possible from the hinge. What is the magnitude and direction of the force that child B must exert if the door does not move? A) Force of magnitude F in the north direction B) Force of magnitude F in the east direction C) Force of magnitude F/3 in the north direction D) Force of magnitude F/3 in the west direction
