solution


consider a semicircular ring of radius R which is uniform.a uniform semicircular ring is symmetric about Y-axis so its its x coordinate of center of mass will be zero .


diagram for this question can be drawn as




y coordinate of the semicircular ring can be written as


y=2Rπy=\frac{2R}{\pi}


therefore center of mass is at (0,2Rπ)(0,\frac{2R}{\pi})
