We know that either team is winning which means that the cumulative forces (sum of each girl force) on both teams are equal.

This means,

[tex]250 + 250 + 250 + 250 = 260 + 260 + 260 + x[/tex]

being x the force of the fourth girl on the east team.

Solving to x, you get

[tex]x = (250 + 250 + 250 + 250) - (260+260+260)

x = 1000 - 780

x = 220[/tex]

The fourth girl on the east is pulling with a force of 220N.

Answer:

The force applied by fourth girl in east team is 220 N.

Explanation.

If neither side is wining, it means that force applied on both sides are equal.

Total force by team west = 250 N * 4 = 1000 N

Total force of 3 girls on east side = 260 N * 3 = 780 N

As we know the east team apply total force of 1000 N.

Force applied by the fourth girl in east team = 1000 N - 780 N = 220 N
