Question
A thin non-con ducting 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 pl ane with the effect of an external force. The rails at the edges of the
inclined 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 pl ane). Before
sliding, the rod stays at the distance 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 magneti c flux pa ssing 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
