Question

A small mass M attached to a string slides in a circle (x) on a frictionless horizontal table, with the force F providing the necessary tension (see figure). The force is then increased slowly and then maintained constant when M travels around in circle (y). The radius of circle (x) is twice the radius of circle (y).

a. M's angular momentum at x is .... that at y.

b.While going from x to y, there is no torque on M

c.As M moves from x to y, the work done by F is .... 0.

d.M's kinetic energy at x is half that at y.

e. M's angular velocity at x is half that at y.

**all answers are either true, false, less than, greater than or equal to**
