In the figure, a copper rod of mass 210 grams rests on a pair of rails 85 cm apart. The rod is perpendicular to the rails. The rails are bare metal and carry a current of 40 amps, which of course is shared by the rod. The coefficient of friction is .65. A .055 T magnetic field exists, pointing almost straight up, making an angle of 25 degrees with the vertical. Find the acceleration of the rod.
