5. In the diagram below, a conducting 400 3 rod with a length of 35 cm moves with a constant speed of 2 nuts on a set of conducting rails. The magnetic eld is I15 Tand the coefficient of friction between the rod and the rails is [1.3. If the rod has a resistance of 3 , calculate the magnitude of the applied force needed to move the rod on the rail. [1'10] E. A certain planet has a radius of 3.5 it 105 n1 and a mass of 6.3 I 1023 kg. An unpowered projectile is fired vertically upwards from the surface of this planet. To what height above the surface will the projectile rise if it leaves the surface at 1500 mfs? [IE5]
