Question: What is the effect of increasing the radius of a rolling object on its moment of inertia?

Options:

1. It decreases the moment of inertia.
2. It increases the moment of inertia.
3. It has no effect on the moment of inertia.
4. It depends on the mass of the object.

Correct Answer: It increases the moment of inertia.

Solution:

The moment of inertia increases with the square of the radius, as seen in the formula I = k m r^2, where k is a constant depending on the shape.
