How does newton’s third law of motion relate action and reaction forces? they produce a net force of zero. they are equal and opposite. they are unaffected by gravity.

The correct answer option is: they are equal and opposite.

Explanation:

A force is a push or a pull which acts upon any object as a result of its interaction with another object where the forces are called action and reaction.

And according to the Newton's third law: for every action, there is an equal and opposite reaction.

For example, if a bat hits a ball with a 1000-N force, the force exerted on the bat will also be equal to 1000 N but in opposite direction.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
