ABC is a part of ring having radius `R_(2)` and ADC is a part of disc having inner radius `R_(1)` and outer `R_(2)`. Part ABC and ADC have same mass. Then center of mass will be located, from the centre.

A

`((R_(2)-R_(1))(2R_(1)+R_(2)))/(3pi(R_(1)+R_(2))) ("above")`

B

`((R_(2)-R_(1))(2R_(1)+R_(2)))/(3pi(R_(1)+R_(2))) ("below")`

C

`(2R_(1)+R_(2))/(3pi)("above")`

D

`(2R_(1)+R_(2))/(3pi)("below")`
