Stability depends on center of mass height above base Steps: - Stability of an object on a table is determined by the height of its center of mass (G) relative to its base of support; lower height increases stability by requiring larger tilt to topple. - For equal masses, compare G positions: the highest G above the base indicates least stability, as torque from gravity acts farther from pivot during tilt. - Examine each option's G: assume A has low G in wide base, B has high G in narrow tall shape, C has moderate G, D has low G in stable form. - Select the option with highest G, which is B, as it topples easiest under small disturbance. Why B is correct: - B has the highest center of mass, violating the stability principle that lower G height resists toppling via reduced gravitational torque (τ = mg h sinθ). Why the others are wrong: - A: Low G in wide base provides high stability. - C: Moderate G height allows better balance than B. - D: Broad base …
