WebMath Advanced Math An object occupies the volume of the upper hemisphere of x² + y² +2²=4 and has density z at (x, y, z). Find the center of mass. z=y=0,2 = 16/15. An object occupies the volume of the upper hemisphere of x² + y² +2²=4 and has density z at (x, y, z). Find the center of mass. z=y=0,2 = 16/15. WebOct 18, 2024 · when measured from the center of a sphere that contains the hemisphere. Obviously, the CM is along the line of symmetry (here called the z -axis) of the hemisphere. If I want to think in terms of stacking disks I write z C M = ∫ d z ( R 2 − z 2) z ∫ d z ( R 2 − z 2) = 3 8 R which is of course the same result.
WebThe Centre of masses of different bodies is given below in the table : EXPLANATION: From the above table, it is clear that the center of mass of a hollow hemisphere is at a distance of R/2 from the center.
