Problem 19Q

Two spheres look identical and have the same mass. However, one is hollow and the other is solid. Describe an experiment to determine which is which.

Step-by-Step Solution:

Step-by-step solution

Step 1 of 1

Let the spheres spin on the table. The sphere which spins at a lower rate will be the hollow sphere. This is because in a hollow sphere, the air inside tries to get away from the axis of rotation. Therefore its moment of inertia increases causing reduction in angular velocity.

As the torque is constant (torque = moment of inertia x angular velocity) for both the spheres; hence in case of a solid sphere, it will rotate more or less like a rigid body with a greater angular velocity.
