6) YA S Z. A thin non-conducting rod of mass m and length L = 60 cm slides frictionl essly at a constant speed V = 0.8 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 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 = 40° with the horizontal plane (xz pl ame). Before sliding, the rod stays at the distance S = 7 m measured from the bottom edge of the inclined plane. The inclined plane and the rod are under the effect of a uniform magneti c fiel d given by B = 1,81 + 2,6J -2k(T). 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= 5s After the rod starts to slide, A) 1.50 Wb B) 7.53 Wb C) 0.083 Wb D) 0.147 Wb E) 1.67 Wb
Same situation as in the previous two problems this time the magnet s mass is 7.20 kg and the magnetic force pulling it to the right is 115.1 N. The length of the cord is 1.39 m, and the ceiling is 3.10 m above the floor. Suppose that you cut the cord and the magnet falls to the floor while still being pulled to the right by the force of 115.1 N. How long will it take the magnet to hit the floor? 0.696 s 0.418 s 0.835 s 0.627 s
