A) m1 = 4 кг, m2 = 2 кг. Is the balance correct?

Analysis:

• The first image shows a balance scale. On the left side, there is a mass labeled m1 = 4 кг placed at the 4 mark. On the right side, there is a mass labeled m2 = 2 кг placed at the 2 mark.
• For the balance to be correct, the product of the mass and its distance from the fulcrum (lever arm) must be equal on both sides.
• Left side moment: 4 кг * 4 units = 16 unit-kg
• Right side moment: 2 кг * 2 units = 4 unit-kg
• Since 16 is not equal to 4, the balance is incorrect.

Answer: Incorrect
