In a physics experiment, a metal bar is balanced on a fulcrum. A 5.0 kg mass is placed on the bar, 45.0 cm from the fulcrum, and on the same side a 2.0 kg mass is placed an unmeasured distance away from the fulcrum. Another mass (12 kg) is placed on the other side of the fulcrum, 50.0 cm away. How far away is the 2.0 kg mass from the fulcrum?
