Question

A wire is bent to form a semicircle of radius a . The wire rotates about its one end with angular velocity ω . Axis of rotation being perpendicular to the plane of the semicircle. In the space, a uniform magnetic field of induction B exists along the axis of rotation, as shown in figure. Then, potential difference between P and Q is equal to 2 B ω a 2, potential difference between P and Q is equal to 2 π 2 B ω a 2, P is at higher potential than Q, none of these
