comment What is the exact definition of center of gravity?
You are assuming that the gravitational field has the same magnitude at all points on a horizontal line. It need not be that way. Though I agree that the second definition alone won't suffice, it could be a number of different points.

comment What is the exact definition of center of gravity?
Doesn't the center of gravity depend on the gravitational field? In a uniform gravitational field, I agree that it is (∑x⃗ imi/∑mi) but what about a non-uniform gravitational field?

Was the aim of Newton's experiment to explain lack of dispersion through a glass slab??

@Manishearth But the path of light would be different if you assume two prisms - what happens to the extra bending at the boundary between prisms? And if you say that there's no extra bending because there's no air, then how is that any different from just a glass slab? It doesn't give a 'new' explanation.. :/
