Question

Two boys pull a rope from two ends with a force equal to 10N each what is the resulant force

Answer 1

AnsweR :

If two boys pull a rope from the two ends with the equal force of 10 N, each. So, we have to find resultant force.

As we know that the rope goes to the direction where the more force is applied to the end of the rope. But if the forces are equal and are in the opposite direction then the resultant of the force will be in equilibrium, it means the rope will remains in its initial position only if the forces are equal and Opposite.

Where as if the force on one end is more than the other end. in this case we will just simply subtract the greater force from the smaller force.

But here forces are equal of 10 N

⇒Resultant = 10 - 10

⇒Resultant = 0 N

• So, the resultant force will be zero.

______________________

$\bf \huge. To \: Find \:$

• what is the resulant force

Solve:-

• While many people would like to simply add the forces from each end to get a total force, this is fundamentally incorrect.

• This is an application of Newton's Third Law: "For every action there is an equal and opposite reaction."

• The only way someone on one end of the string can exert a force of 10 N on the other end of the string is of the other end of the string exerts a 10 N force in the opposite direction.

• Suppose I hang a 1 kg mass from a spring scale.

• This pulls with a force of approximately 10 N. Next, remove the weight and attach the spring scale to a wall. Pull on the scale until it reads 1 kg.

• That's the same 10 N force that the weight (and gravity) exerted downward when it was hanging.

• Lastly, consider what would happen if you attached a second spring scale to the wall and the end of the string to that spring scale.

• When you pull one hard enough to make it read 1 kg, the spring scale on the opposite end will also show 1 kg.

They are indicating equal forces in opposite directions.
