10. A hoop, solid sphere, and solid cylinder each have the same mass and same radius. When rolling down the same incline, which has the greatest torque from gravity on it?
a. the hoop
b. the sphere
c. the cylinder
d. They all have the same torque.
Homework Answers
Torque = force * lever arm
Here lever arm is radius which is same for all three.
force = mgsin
as mass is same for all three and incline is also same, this means force is same in all three case.
Therefore,
torque is same for all three.
