Physics - Center of Mass Question with Solution | TestHub
Match the physical quantities related to the center of mass of various uniform objects with their correct values.
List - I | List - II |
|---|---|
(P) Distance of COM of a uniform semicircular wire of radius R from its center | (1) |
(Q) Distance of COM of a uniform solid hemisphere of radius R from its flat base | (2) |
(R) Distance of COM of a uniform hollow hemisphere of radius R from its flat base | (3) |
(S) Distance of COM of a uniform solid cone of height H from its base | (4) |
Options:
Answer:
Solution:
For a uniform semicircular wire of radius R, the COM is at from the diameter, which is from the center along the axis of symmetry. For a uniform solid hemisphere of radius R, the COM is at from the flat base. For a uniform hollow hemisphere of radius R, the COM is at from the flat base. For a uniform solid cone of height H, the COM is at from the base.
