A uniform steel rod has mass 0.300 kg and length 40.0 cmand ishorizontal. A uniform sphere with radius 8.00 cm and mass 0.700 kgis welded to one end of the bar, and a uniform sphere with radius6.00 cm and mass 0.580 kg is welded to the other end of the bar.The centers of the rod and of each sphere all lie along ahorizontal line.
Part A
How far is the center of gravity of the combined object from thecenter of the rod?
Express your answer with the appropriate units. Enter negativevalue if the center of gravity is toward the 0.700 kg sphere andpositive value if the center of gravity is toward the 0.580 kgsphere.
