The statement "The centre of gravity of a body may not be necessarily on the body" is indeed correct. Here's why:

1. The center of gravity is the point where the weight of an object is evenly dispersed and all sides are in balance. It's the average location of the weight of an object.

2. For a uniform solid object, the center of gravity is at the geometric center. For instance, the center of gravity of a solid cube or sphere is at its geometric center.

3. However, for irregularly shaped or non-uniform density objects, the center of gravity may not be on the object itself. A classic example is a donut or a ring. The center of gravity is at the geometric center, which is an empty space not occupied by the material of the object.

4. Similarly, for a hollow object, the center of gravity is in the space enclosed by the object, not in the material of the object itself.

5. Also, in a system of objects, like a solar system or a molecular structure, the center of gravity may not be on any of the objects themselves, but somewhere in the space between them.

So, the center of gravity is not necessarily on the body itself, it depends on the shape and density distribution of the object.
