A ladder leans against a wall at an angle 0 above the horizontal as shown in figure. The ladder is uniform with mass M and length L. Assume that the ladder is at rest due to friction between the ladder and ground. What i the torque exerted by gravity on the ladder about the axis of rotation shown (horizontal and parallel to the wal axis through its base)? (A) zero (B) Mg cos 0 (C) MgL (D) MgL cos 0 (E) M9L sin e F) MgL 5) Mg sin 0 ) One needs the coefficient of friction to answer this problem
