When all of the internal forces on an object (the forces which one part of
the object exerts on another part) are added up, the total is always equal to
(A) the difference between odd and even numbered forces.
(B) the last force added.
(C) zero.
(D) (average force) times (square root of number of parts).
When all of the internal forces on an object (the forces which one part of
the object exerts on another part) are added up, the total is always equal to
(A) the difference between odd and even numbered forces.
No. Numbering the forces does not matter.

When all of the internal forces on an object (the forces which one part of
the object exerts on another part) are added up, the total is always equal to
(B) the last force added.
No. The forces come in action-reaction pairs which cancel.
When all of the internal forces on an object (the forces which one part of
the object exerts on another part) are added up, the total is always equal to
(C) zero.
Yes. The action-reaction pairs all cancel.
When all of the internal forces on an object (the forces which one part of
the object exerts on another part) are added up, the total is always equal to
(D) (average force) times (square root of number of parts).
No. This answer would actually make sense if the
internal forces were random, but they are not.
