Physics
Two objects have the same mass but different shapes. Which object would have a higher centre of gravity?
- the one with a larger base
- the one with a smaller base
- both would have the same centre of gravity
- it depends on the material of the object.
Answer
the one with a smaller base
Reason — An object with a larger base of support will have a low centre of gravity because the distribution of mass is spread out over a larger area, which tends to lower the center of gravity whereas that with a smaller base will have a higher centre of gravity because the mass is concentrated over a smaller area.
