(See the picture attached)A conducting rod with mass (m) and lenght (l) is sliding with no friction along 2 conducting rails. A generator that is attached to the rails provides current (I) that flows thru the rails and rod. Find an expression for acceleretion of the bar in terms of current (I), mass (m), and lenght (l)
