A thin wire AC shaped as a semi-circle of diameter d rotates with a constant angular frequency (ω) in a uniform magnetic field of indcution B. The vector ω is parallel to B and the rotation axis XY passes through the end A of the wire and is perpendicular to the diameter AC (see Fig.). B is directed left to right in the plane of the paper. The value of the line intergral I = ∫E ⋅dr taken along the wire form the point A to the point C will be ωBd2/ ?. What integer should be inserted in place of question mark.
