Question

A closed circuit is formed by a fixed U-shaped conductor and a sliding bar. as shown in the figure. The bar remains in contact with the conductor but is pulled down by gravity. The bar has a mass m = 2.6 grams. a length 1 = 14 cm. and a resistance R = 0.0018 Ohm. The U-shaped conductor has a resistance much smaller than this. (Figure 1) The entire circuit is placed in a uniform horizontal magnetic field B = 0.070 T . and the bar allowed to fall. Find the resulting terminal speed of the bar (neglecting air resistance). Express your answer to two significant figures and include the appropriate units.
