Center of mass of hemispherical shell
WebFind the mass and center of mass of the object. (Note that the object is just a thin shell; it does not occupy the interior of the hemisphere.) We write the hemisphere as r ( ϕ, θ) = cos θ sin ϕ, sin θ sin ϕ, cos ϕ , 0 ≤ ϕ ≤ π / 2 and 0 ≤ θ ≤ 2 π. So r θ = − sin θ sin ϕ, cos θ sin ϕ, 0 and r ϕ = cos θ cos ϕ, sin θ cos ϕ, − sin ϕ . Then WebNotice that the hemisphere exhibits rotational symmetry about the $z$-axis, and argue that the center of mass vector should respect this symmetry. This can be argued rigorously …
