In an action-reaction pair
a. action force is exerted first

b. action force and the reaction force are equal in magnitude and act in the same direction.

c. action force and the reaction force are contact forces only.

d. action force and the reaction force act on two different objects.

Answer:

c. action force and the reaction force are contact forces only.

Explanation:

The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

  • In an action-reaction pair, action force and th reaction force act on two different objects.
  • Newton's Third Law of Motion states, "To every action, there is an equal and opposite reaction; action and reaction act on two different bodies."
  • The first option is incorrect because action and reaction forces act simultaneously.
  • The second option is also false because they act in opposite direction.
  • The third option is wrong because for action-reaction force, physical contact is not necessary.

Answer:

d. action force and the reaction force act on two different objects.
