Is the center of mass of the dumbbell in (Figure 1) at point a, b, or c? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. significantly greater than significantly smaller than equal to the product the ratio closer to the large sphere closer to the small sphere equidistant from both spheres point a point b point c Reset Help As suggested by the figure, the larger sphere is more massive than the smaller sphere. If we suspend the dumbbell from its center of gravity, the counterclockwise torque due to the large sphere must be the clockwise torque due to the small sphere. Since torque is of force and its moment arm, the center of gravity should be This occurs at
