Problem 29.65 You are conducting an experiment in which a metal bar of length 8.00 cm and mass 0.150 kg slides without friction on two parallel metal rails (Figure 1). A resistor with resistance R=0.700 is connected across one end of the rails so that the bar, rails, and resistor form a complete conducting path. The resistances of the rails and of the bar are much less than R and can be ignored. The entire apparatus is in a uniform magnetic field B that is directed into the plane of the figure. You give the bar an initial velocity v = 20.0 cm/s to the right and then release it, so that the only force on the bar then is the force exerted by the magnetic field. Using high-speed photography, you measure the magnitude of the acceleration of the bar as a function of its speed. Your results are given in the table: t (cm/s) 20.0 16.0 14.0 12.0 10.0 8.0 a (cm/s²) 6.2 4.9 4.3 3.7 3.1 2.5 BX Figure a XR 6.00 cm 1 of 1
