The explanation details how to adjust weights on a triple beam balance to maintain balance during measurement.
Explanation:
A triple beam balance is a type of balance that consists of a beam with three parallel beams, each carrying a sliding weight. When using a triple beam balance, move the weight back to the previous notch or groove if the pointer on the balance swings past the center mark in either direction, indicating an imbalance.
For example, if you are weighing an object and the pointer moves too far to the right, you need to move the weight on the corresponding beam back to a lower notch until the pointer settles at the center position.
