Question
Which of the following statements correctly expresses the parallel axis theorem?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The parallel axis theorem states that the moment of inertia I about any axis parallel to an axis through the center of mass is equal to the moment of inertia about the center of mass axis I_cm plus the product of the total mass M and the square of the perpendicular distance h between the axes: I = I_cm + Mh².
Hint
Recall how the moment of inertia changes when the axis of rotation is shifted parallel to an axis through the center of mass.
