A triatomic molecule is oriented as follows along the x-axis: mass m is at the origin,mass 2m is at x = a,and,mass 3m is at x = 2a.What is the moment of inertia of this molecule about the y-axis? A)2ma² B)3ma² C)12ma² D)14ma²

Question

Quizplus · Accepted Answer

The moment of inertia I about the y-axis is calculated as I = Σ mi * xi^2. For this molecule, I = m*(0)^2 + 2m*(a)^2 + 3m*(2a)^2 = 0 + 2ma^2 + 12ma^2 = 14ma^2.
