70. A pencil rests against a corner, as shown below. The sharpened end of the pencil touches a smooth vertical surface and the eraser end touches a rough horizontal floor. The coefficient of static friction between the eraser and the floor is pu, = 0.7 . The center of mass of the pencil is located87cm from the tip of the eraser and(3 .0 cm from the tip of the pencil lead. Find the minimum angle 0 for which the pencil does not slip. Please enter your Auswer in degres 13 cm -8.7 cm- CM
