Answer 1

Answer:

Find coordinates of mass center of a semicircular ring of radius r placed symmeric to the y-axis of a Cartesian coordinate system.

Solution: The `y-`axis is the line of symmetry, therefore mass center of the ring lies on it making x-cordinate zero. Distance OC of mass center from center ...

Answer 2

The centre of mass of the ring is given by 2R/π, where R is the radius of the semicircular ring.Hence, the coordinates of the centre of mass of a quarter ring placed in the first quadrant is (XCM,YCM)=(2Rπ,2Rπ). Note: To find centre of mass, always take a small mass into consideration.The coordinates of centre of mass of particles of mass 10,20,30gm are (1,1,1)cm. The position of coordinates of mass 40gm which when added to the system, the position of combined centre of mass be at (0,0,0) are.
