The wire loop `PQRSP` formed by joining two semicircular wires of radii ` R_(1)` and `R_(2)` carries a current `I` as shown . The magnitude of the magnetic induction at the center `C` is ………..

`(mu_(0)I)/2(1/(R_(1))+1/(R_(2)))`

`(mu_(0)I)/4(1/(R_(1))+1/(R_(2)))`

`(mu_(0)I)/2(1/(R_(1))-1/(R_(2)))`

`(mu_(0)I)/4(1/(R_(1))-1/(R_(2)))`
