Explanation of Solution

  Physics for Scientists and Engineers: A Strategic Approach, Vol. 1 (Chs 1-21) (4th Edition), Chapter 12, Problem 1CQ

Center of mass of a body is a point where entire mass of the body is concentrated. It is the average position of all the particles of the object.

The given figure shows the figure of the dumbbell with different weight on both sides. Thus, the center of mass of the dumbbell shift towards the heavier object in case of unequal mass.

Hence, point a is the center of mass of the dumbbell.

Conclusion:

Point a is the center of mass of the dumbbell as it shifts towards the heavier object in case of unequal mass.
