In figure, R is a fixed conducting ring of negligible resistance and radius a. It is hinged at the center of the ring and rotated about this point in clockwise direction with a uniform angular velocity ω. There is a uniform magnetic field of strength B pointing inward and r is a stationary resistance. Then

a magnetic field of 1 T exists. The electric current in the 9 Ω resistance is In figure the wires P 1 Q 1 and P 2 ​Q 2 ​ are made to slide on the rails with same speed of 5 cm /s . In this region
