Question 8 • Physics I

Two teams are playing tug of war. Team A pulls to the right with a force of 450 N. Team B pulls to the left with a force of 415 N. What is the net force on the rope, and what is its direction?

Answer
A
35 N to the right
B
35 N to the left
C
865 N to the left
D
865 N to the right

Explanation

The teams pull in opposite directions, so subtract the smaller force from the larger: 450 N − 415 N = 35 N. The larger force is Team A’s pull to the right, so the net force is 35 N to the right. This matches choice A, “35 N to the right.”
