    What do you think? What's the definition of center of mass?

    Well The centre of Gravity I believe is the point of which all of the weight of the object acts upon.

    That's true. Another way to define it is as the average location of the mass in an object.

    Read this: Center of Mass

    Yes but how would you solve the question then

    Yes I did

    But surely there is a less complicated way of working out the centre of mass on this question

    Well, what do you think?

    Start with the symmetric dumbbell. Where do you think the center of mass would be?

    (The link I gave tells you how to calculate the center of mass.)
