The given assembly made of conducting wire is rotated with a constant angular velocity w about a real axis AC as shown in figure. AD part of assembly is quarter circle of radius R and DB is straight and parallel to axis AC. The magnetic field B? exists vertically upward parallel to axis AC .Find the potential difference between points A and B(only the magnitude).Options are (A) B?( w R 2 /2) (B) B?( w ? R 2 /4) (C) B? w (2 R 2 ? ? R 2 /4) (D) zero
