Two conducting rails 30cm apart rest on a 5.0(degree)ramp. They are joined at the bottom by a 0.60 ohm resistor,and at the top a copper bar of mass, 0.040kg is laid across therails. The hole apparatus is immersed in a vertical 0.55 Tfield. What is the termal velocity of the bar as it slidesfrictionless down the rails?
