Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 165 N at a distance of 0.400 m from the hinges, and the second pushes at a distance of 0.450 m. What force must the second exert to keep the door from moving? Assume friction is negligible.
