`AB` is a resistanceless conducting rod which forms a diameter of a conducting ring of radius `r` rotating in a uniform magnetic field `B` as shown in figure. The resistance `R_(1)` and `R_(2)` do not rotate. Then the current through the resistor `R_(1)` is

A

`(Bomegar^2)/(2R_1)`

B

`(Bomegar^2)/(2R_2)`

C

`(Bomegar^2)/(2R_1R_2)(R_1+R_2)`

D

`(Bomegar^2)/(2(R_1+R_2))`
