Question
The moment of inertia of a point mass m located at a perpendicular distance r from an axis of rotation is
Correct Answer
Option B is the correct answer.
Detailed Explanation
For a single point particle, the moment of inertia I about an axis is defined as the product of its mass and the square of its perpendicular distance from the axis: I = mr².
Hint
Moment of inertia depends on both mass and how far that mass is distributed from the axis. This dependence involves the square of the distance.
