Question

Write the position of the centre of gravity for a hollow cone, a hollow sphere, and a parallelogram.

Answer 1

• Hollow Cone: The centre of gravity lies on its central axis, at a vertical height of `h/3` from its base, where h is the total height of the cone.
• Hollow Sphere: The centre of gravity lies exactly at its geometric centre.
• Parallelogram: The centre of gravity lies at the point of intersection of its two diagonals.
