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

c.) the ball exerts a force
- upward to the right on the player
- downward on the Earth
- downward to the left on the player
- downward to the right on the player
- upward on the Earth
d.) m exerts a force
- upward on M
- to the left on M
- to the right on M
- downward on M
e.) ?q exerts a force
- downward on Q
- to the right on Q
- upward on Q
- to the left on Q
f.) the iron exerts a force
- upward on the magnet
- to the right on the magnet
- downward on the magnet
- to the left on the magnet
Explanation / Answer
a) Left on hand & right on wall
b) down & left on handle, upward on earth due to gravitational attraction
c) down and right on player, upward on earth
d) [dont know what it means by field force] probably left on M
e) to the left on Q
f) to the left on the magnet
[(b) is definitely -not- downwards on the earth]
