A conducting rod PQ of mass M rotates without friction on a horizontal plane about O as circular rails of diameter 1 The centre O and the R I at P periphery are connected by resistance R The system is located in a uniform magnetic field perpendicular to the loop At t 0 PQ starts rotating clockwise with angular velocity Then a Magnitude of current as a function of time is Bw 1 e 8R b The charge through the resistance is B c The charge through the resistance is d None of the above is correct 000 M 3B 2000 M 5B
