A pair of parallel conducting rails lie at right angle to a uniform magnetic field of 2.0 T as shown in the fig. two resistor 10 Ω and 5 Ω are to slide without friction along the rail. The distance between the conducting rails is 0.1 m. Then

A straight wire of length L is bent into a semicircle. It is moved in a uniform magnetic field with speed v with diameter perpendicular to the field. The induced emf between the ends of the wire is
