A conducting ring of radius r is rolling without slipping with a constant angular velocity ω (figure). If the magnetic field strength is B and is directed into the page then the emf induced across PQ is

then rod Q Two identical conductors P and Q are placed on two friction less rails R and S in a uniform magnetic field directed into the plane. If P is moved in the direction shown in figure with a constant speed
