15. What are the factors on which
the centre of mss of a body
depend? Write the position of
centre of mass of the following

Answer 1

Answer:

In all the four cases, as the mass density is uniform, centre of mass is located at their respective geometrical centres.

i) Sphere - Centre of Sphere

ii) Cylinder - Middle Point on axis of cylinder

iii) Ring - At centre of ring (Outside the ring)

iv) Cube - At point of intersection of diagnols

No, it is not necessary that the centre of mass of a body should lie on the body. For example, in case of a circular ring, centre of mass is at the centre of the ring, where there is no mass.
