Emma and Erika push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. Emma pushes with a force of 16.5 N at a distance of 0.65 m from the hinges and Erika pushes at a distance of 420 cm. What force must Erika exert to keep the door from moving? Let’s assume friction is negligible.
