Question

A hollow sphere and a uniform solid sphere have the same radius and are rotating with the same angular velocity. The hollow sphere has twice as much rotational energy as the solid sphere. If M is the mass of the hollow sphere then the mass of the solid sphere is 5M/6 5M/3 M/2 3M/5 6M/5

Step 1

Given that the rotational energy of the hollow sphere is \( \frac{1}{2} I \omega^2 = \frac{1}{2} \cdot \frac{2}{3} M \omega^2 = \frac{1}{3} M \omega^2 \). Show more…
