Give an example each for a body, where the centreof mass lies inside the body and outside the body.

Sure, here are the examples:

1. A body where the center of mass lies inside the body: A perfect example of this is a uniform sphere, like a solid bowling ball. The mass is distributed evenly throughout the object, so the center of mass is in the exact center of the sphere.

2. A body where the center of mass lies outside the body: A good example of this is a boomerang or a horseshoe. These objects have a shape that is not uniform, and the mass is not evenly distributed. Therefore, the center of mass lies in the space between the two arms of the boomerang or the horseshoe, which is technically outside the physical material of the object.
