The masses attached to the ends of this (very lightweight) bar are 2.2kg for A and 1kg for B. Assume the distance L₁ from A to the fulcrum is 1.3 m. What is the length L2 in meters (assuming the bar is in equilibrium)? Enter two digits after the decimal point (unless they are zero), and don't enter the unit.
