15)A metal bar with length LR =5N is placed on fri ctionless metal rails that are inclined at an angle Ø = 50°above the horizontal. The rails have negligible resistance. A uniform magnetic= 0.50 m, mass m = 80 gram, and resistance=0.50T is directed upward as shown in Figure. The bar isfield of magnitude Breleased from rest and slides down the rails. After the terminal speed (constant%3Dspeed) has been reached, at what rate is electrical energy being converted tothermal energy in the resistance of the bar? (g = 10 m/s²).A) 26.01 W B) 72.70 WC) 32.55 W D) 122.86 WE) 127.55 W

We need to calculate the power converted to thermal energy once the terminal speed is reached.
