A3.00-m-long ladder, weighing 200 n, leans against a smooth vertical wall with its base on ahorizontal rough floor, a distance of 1.00 m away from the wall. the ladder is not completelyuniform, so its center of gravity is 1.20 m from its base. what force of friction must the floor exerton the base of the ladder to prevent the ladder from sliding down
