Force and Weight

Students are playing tug-of-war. If group B pulls the rope to the right with a force of 400 N and group A pulls the rope to the left with a force of 250 N, what will happen to the ribbon in the middle of the rope?

• The ribbon will move to the left and group A will win the tug-of-war.

• The ribbon will move to the left and group B will win the tug-of-war.

• The ribbon will move to the right and group B will win the tug-of-war.

• The ribbon will move to the right and group A will win the tug-of-war.
