Question

A chair has four narrow legs holding it up. The same model of chair is next to it,

but the legs have been removed so that the entire base of the chair rests on the floor
Which is true, assuming the chairs have the same mass?

Answer 1

The topics discussed pertain to Physics, covering mass, equilibrium, forces, and gravity. Acceleration under equal force indicates differences in mass, and the wider base of a chair without legs suggests greater stability.

Step-by-step explanation:

The subject matter discussed here relates to Physics, specifically to the concepts of mass, equilibrium, external forces, and the principle of gravity. The discussion involves understanding the mass of objects by observing their acceleration under an external force, the essence and function of a chair, the concept of equilibrium in physical objects, and the implications of a thought experiment on the equivalence principle by considering a scenario where heavy objects fall faster than lighter ones.

In the context of the chair legs, the chair with a wider base (no legs) would likely be more stable when a side force is applied, as the center of gravity is less prone to exceed the base area compared to a chair with narrow legs. This is related to the concept of equilibrium and center of gravity in Physics.
