A metal bar with length L = 0.40 m ,mass m = 200 gram, and resistance R = 10 N is placed on frictionl ess metal rails that are inclined at an angle Ø = 45° above the horizontal. The rails have negligible resistance. A uniform magnetic field of magnitude B = 1.40T is directed upward as shown in Figure. The bar is released from rest and slides down the rails. After the terminal speed (constant speed) has been reached, at what rate is electrical energy being converted to thermal energy in the resistance of the bar? (g = 10 m/s²).
