MCQ
Action and reaction:
  1. Act on two different objects.
  2. Have equal magnitude.
  3. Have opposite directions.
  4. Have resultant zero.
  • A
    Only $A$
  • B
    $A$ and $B$
  • C
    $B$ and $D$
  • ✓
    All of the above
✓

Answer

Correct option: D.
All of the above

The two forces $\overrightarrow{\text{F}}$ and $-\overrightarrow{\text{F}}$ connected by Newton's third law are known as action-reaction pair.
For example, when a man jumps out from a ferry, he applied some force on the ferry. So, the action force in this case is the force applied by the man and the reaction is the force exerted by the ferry on the man. Both the forces act upon different objects $($the man and the ferry$)$ but have equal magnitudes and opposite directions. As a result, their resultant is zero.
