The force needed to lift a chair is the force with the greatest magnitude.
Based on the given options, the force with the greatest magnitude is "the force needed to lift a chair."
To determine which option has the force with the greatest magnitude, you need to analyze the information provided for each option. The magnitude of a force refers to its strength or size.
In this case, the information provided for each option is the force needed to lift various objects. To compare the magnitudes of the forces, you can consider the weights of the objects.
The weight of an object is the force exerted on it due to gravity. It can be calculated using the formula:
weight = mass × acceleration due to gravity
Since we don't have specific mass values for the objects mentioned in the options, we can make an assumption that the mass of each object remains constant. In this case, you can compare the magnitudes of the forces by assuming a constant mass.
Based on the options given, a textbook is usually heavier than a hairbrush, a chair is typically heavier than a textbook, and a pencil is usually the lightest among these objects.
Therefore, the force with the greatest magnitude would be the force needed to lift a chair, as chairs are generally heavier than textbooks, hairbrushes, and pencils.
In summary, to determine the force with the greatest magnitude in this scenario, you analyze the weights of the objects and compare them, concluding that the force needed to lift a chair has the highest magnitude.
