SUMMARY
The center of mass for a system consisting of a 4 kg rod and a 4 kg sphere attached at one end can be calculated using the formula MXcm = m1x1 + m2x2. Given the rod's length of 24 m and the sphere's radius of 1.5 m, the center of mass is determined by balancing the torques around the pivot point. The equilibrium condition requires that the clockwise torque equals the anticlockwise torque, allowing for the calculation of the center of mass location along the rod.
