A rectangle is bent on two sides at 90º so that one end lies along the xy-plane while the other end lies along the xz-plane. The length a = 10 cm and b = 30 cm. At t = 0, a magnetic field of strength B = 0.1 T lies in the yz-plane and points at an angle Ɵ = 30 and 10 ms later the field points in the opposite direction. The EMF induced in the rectangle is
A) 10.4 V.
B) 6.0 V.
C) 12 V.
D) 8.2 V.
E) None of these is correct.
