Problem 1: A rod of m = 1.35 kg rests on two parallel rails that are L = 0.75 m apart. The rod carries a current going between the rails (bottom to top in the figure, into the page) with a magnitude I = 4.8 A. A uniform magnetic field of magnitude B = 0.15 T pointing upward is applied to the region, as shown in the figure. The rod moves a distance d = 0.25 m along the rails in a given time period. Ignore the friction on the rails. Part (a) Express the magnitude of the magnetic force F on the rod, in terms of the length L, current I, and magnetic field B. Expression : F = Select from the variables below to write your expression. Note that all variables may not be required. a, y, T, 0, B, d, F, g, h, I, j, L, m, P, t Part (b) Calculate the numerical value of F, in newtons. Numeric : A numeric value is expected and not an expression. F = Part (c) Which direction does the rod move? MultipleChoice: 1) To the left. 2) To the right. Part (d) Determine the work done on the rod during its motion, in terms of the magnetic force F and the distance traveled d. Expression : W =
