ratio of maximum shear to bending stress

Question

Consider a simply supported beam of length 50h, with a rectangular cross-section of depth h, and
width 2h. The beam carries a vertical point load P, at its mid-point. The beam carries a vertical
point load P, at its mid-point. The ratio of the maximum shear stress to the maximum bending
stress in the beam is

(a) 0.02                                (b) 0.10
(c) 0.05                                (d) 0.01
