Centre of mass of sphere

WebSep 12, 2024 · Relevant Equations: for this derivation, I decided to think of the solid hemisphere to be made up of smaller hemispherical shells each of mass at their respective center of mass at a distance r/2 from the center of the base of the solid hemisphere. also, I have taken the center of the base of the solid hemisphere to be the origin. WebCentre of mass of the hollow sphere is also located at the geometrical centre of the sphere if the mass is uniformly distributed. The reason is the same as in the solid sphere: if we go in any direction from the centre we will interact with the same mass at the same distance from the centre.
