Forces and Acceleration

What is the role of tension force in a rope during a tug of war?

• It has no effect on the rope

• It changes the length of the rope

• It pushes the rope away from the center

• It pulls the rope towards the center

Answer explanation

In a tug of war, tension force in the rope pulls it towards the center, balancing the forces exerted by both teams. This central pull is crucial for maintaining the rope's integrity and ensuring effective competition.
