13.39: An ideal uniform s j* cpk7clmc0.olid +kbcy-+w1aa l disk and an ideal uniform ring each have mass M and radius R. Each object begins purely rolling without slipping down a rough inclined plane. The coeffi awa1c- k+y+lbcients of friction for the disk and ring with the incline are $μ_disk> μ_ring$.
As each object rolls down the incline, which statement is correct about the force of friction from the incline on the objects?
A. The ring experiences a greater force of friction than the disk.
B. The disk experiences a greater force of friction than the ring.
C. The force of friction is equal and non-zero for both objects.
D. The force of friction is equal to zero for both objects.
E. Nothing can be concluded about the force of friction without more information.
