As shown in the figure below, a bead starts from rest at point A and slides along a straight wire to point B while a constant force of friction acts on the bead. Next, the bead starts from rest at point A again and slides along a curved wire to point B. subject to a force of friction with the same constant magnitude. Which of the following statements are correct? 1. In both cases, the bead.reaches point 8 with the same speed. 11. The work done by the force of friction on the bead is the same for both cases. III. The work done by the force of gravity on the bead is the same for both cases. 0 II only III only I and III only I only I, II, and III
