Question

1 pts a solid sphere and a hollow sphere have the same mass and radii. the two spheres are spun with matching angular velocities. which statement is true? i. the hollow has the greater angular momentum ii. the solid sphere has the greater angular momentum. iii. the angular momentum is the same for both spheres. iv. the moment of inertia is the same for both spheres. group of answer choices iv i ii iii

Answer 1

Only (i) is true.

I (solid sphere) = 2/5 M R^2

I (spherical shell) = 2/3 M R^2 (hollow)

The hollow sphere has the greater momentum
