1.A triangular block was placed on each of the weighing scales (labelled as A and B as depicted below). The readings on the weighing scales were then set to 0 kg. Next, a 1 m long ruler that weighs 1 kg was lowered onto these two triangular blocks as shown in the figure below. What is the reading on each weighing scale? (Assume that the weight of the ruler is evenly distributed.)
