Answer:
Required center of mass
Step-by-step explanation:
Given semcircles are,
whose radious are 1 and 4 respectively.
To find center of mass, , let density at any point is and distance from the origin is r be such that,
where k is a constant.
Mass of the lamina=m= where A is the total region and D is curves.
then,
- Now, x-coordinate of center of mass is . in polar coordinate
Then,
- y-coordinate of center of mass is . in polar coordinate
Then,
Hence center of mass
