Question

For a bowling ball, how far apart are the center of gravity and center of mass?

• A. They are at almost exactly the same location.
• B. They are at opposite sides of the object.
• C. They are both at the surface of the object.
• D. They mean the same thing, so they're at the same location, as always.
• E. None of the other answers is correct.

Answer 1

The correct option is A They are at almost exactly the same location.

Centre of mass and of gravity coincide for objects which are small as compared to the radius of the earth.

Note that they don't mean the same thing.
