Ул A thin non-conducting rod of mass m and length L = 60cm, slides frictionl essly at a constant speed V = 0.5 m/s along the rails placed on the surface and at the edges of an inclined plane with the effect of an external force. The rails at the edges of the indined plane are connected with each other via the rail at the bottom edge of the plane, so the rod and rails forms a rectangular closed loop as seen in the figure. The plane of the rails makes an angle 0 = 55° with the horizontal plane (xz plane). Before sliding, the rod stays at the di stance S = 4m measured from the bottom edge of the inclined plane. The inclined plane and the rod are under the effect of a uniform magneti c field given by B = 0.40î + 3ĵ + 0.8k(T). After the rod starts to slide, what will be the magnetic flux passing through the surface formed by the rod, the rails at the edges, and the rail at the bottom edge of the inclined plane at t=4s? A) 1.50 Wb B) 7.53 Wb C) 0.083 Wb D) 0.147 Wb E) 1.67 Wb
