Question

Jo, Daniel and Helen are pulling a metal ring. Jo pulls with a force of 100N in one direction and Daniel with a force of 140N in the opposite direction. If the ring does not move, what force does Helen exert if she pulls in the same direction as Jo?

Can someone help me plz

Answer 1

The ring does not move means that the forces are equal.
Let's call Jo's force x
We have the quation
140 = x + 100
x = 40

Answer 2

an unbalanced force moving everyone in Daniel and Maria's direction
