Question

One or more external forces are exerted on each object enclosed in a dashed box shown in the figure below. Identify the reaction to each of these forces. (Assume that (a), (b) and (c) occur on Earth while (c), (d) and (e) occur far from any outside gravitational influences.  Select all that apply.)

(a) the spring exerts a force (b) the wagon exerts a force      to the right on the wall to the left on the hand downward on the Earth to the left on the wall to the right on the hand upward on the Earth              
upward on the Earth due to contact downward on the Earth due to gravitational attraction downward to the left on the handle downward on the Earth due to contact upward on the Earth due to gravitational attraction upward to the left on the handle (c) the ball exerts a force (d) m exerts a force      upward on the Earth downward on the Earth upward to the right on the player downward to the right on the player downward to the left on the player              
     downward on M upward on M to the right on M to the left on M              
(e) ?q exerts a force (f) the iron exerts a force      to the right on Q downward on Q to the left on Q upward on Q              
        to the left on the magnet to the right on the magnet downward on the magnet upward on the magnet



    
Contact forces Field forces Iron
