    Center of Mass --True and False

    1. The problem statement, all variables and given/known data

    The center of mass of an object....

    1.True or False exists only if the object is round.
    2. True False exists only if the object is symmetric.
    3. True False can be used to represent the location of the object's total mass.
    4. True False can be represented by any point in the object.
    5. True False lies on the axis of symmetry if the object is symmetric.

    2. Relevant equations

    I basically used my knowledge to make an educated attempt at this problem, but I am still getting it wrong can you guide me to figuring it out.

    3. The attempt at a solution

    Yeah, I guess I thought too quickly on #2, I looked back on my notes and found out the object doesn't have to be symmetric. Thanks
