Consider the circuit. shown in the gure. that is made up of the l 52 resistor. the two rails. and the bar connecting the two rails. The bar can slide on the rails to the. left or right. The separation between the rails is 4 m . There is a 5 T magnetic field directed per- pendicularly into the page. An applied force moves the bar to the right. at a constant speed of 3 111/ s. Calculate the applied force required to move the. bar to the right. at. this constant. speed of 3 m/s. Assume the bar and rails have. negligible resistance and there is 110 friction between the bar and the rails. Answer in units of N
