Problem

A small metal ring is held stationary by three cords. Two horizontal cords pull on the ring with

35\,\text{N}

to the east and

35\,\text{N}

to the west. The third cord is vertical and attached to a support above the ring. A student lists the following forces for a free-body diagram of the ring: I.

35\,\text{N}

to the east (cord) II.

35\,\text{N}

to the west (cord) III. Weight of the ring (downward) IV.

35\,\text{N}

upward (force exerted by the ring on the support) Which force should be omitted from the free-body diagram of the ring? a) III only b) I only c) IV only d) None — all four forces should be shown
