Which of the following is the correct formula for moment of inertia?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. I = mr2.
The correct formula for the moment of inertia is I = mr², where I represents the moment of inertia, m is the mass of the object, and r is the distance from the axis of rotation. This formula applies specifically to a point mass rotating about an axis. For other shapes and configurations, the moment of inertia formula will vary depending on the mass distribution and axis of rotation.
