Three physical pendulums, with masses m₁, m₂ = 2m₁, and m₃ = 3m₁, have the same shape and size and are suspended at the same point. Rank them according to their periods, from shortest to longest. A) 1, 2, 3 B) 3, 2, 1 C) 2, 3, 1 D) 2, 1, 3 E) All the above are the same

Question

Quizplus · Accepted Answer

The period of a physical pendulum depends on its moment of inertia and the distance from the pivot to the center of mass, not directly on its mass. Since all pendulums have the same shape and size and are suspended at the same point, their periods are the same.
