Answer
1. Two interacting bodies exert forces which are always equal in magnitude, have the same line of action and are opposite in direction, upon each other. Thus, forces always occur in pairs. 2. If a body $A$ exerts an action force $\vec{F}_{B A}$ on body $B$, then body $B$ also exerts an equal and opposite reaction force $\overrightarrow{ F }_{ AB }$ on body A , simultaneously. 3. Body A experiences the force $\overrightarrow{ F }_{ AB }$ only and body B experiences the force \overrightarrow{\mathrm\{F\}\}_\{\mathrm\{BA\}\} only. 4. Both the forces, action and reaction act at the same instant. 5. Both the forces always act on different bodies. Hence, they never cancel each other. 6. Both the forces do not necessarily arise due to contact i.e., they can be non-contact forces. Example: Repulsive forces between two magnets.
