116. (a) One particle is on the axis, so r= 0 for it. For each of the others, the distance from the axis is r= (0.60 m) sin 60° = 0.52 m. Therefore, the rotational inertia is Imrii==⋅¦2027..kg m2(b) The two particles that are nearest the axis are each a distance of r= 0.30 m from it. The particle “opposite” from that side is a distance
