A solid sphere and a hollow sphere subjected to equal torque.
A solid sphere and a hollow sphere subjected to equal torque.
Two spheres of equal size and equal mass are rotated with an equal amount of torque. One of the spheres is solid with its mass evenly distributed throughout its volume, and the other is hollow with all of its mass concentrated at the edges. Which sphere would rotate faster if the same amount of torque is applied for the same period of time for both?
