The question is incomplete. Here is the complete question.
What happens when two unbalanced forces act on an object?
Consider a game of tug of war between Tim, Elena and Anne. Tim can pull with a force of 70N, Elena can pull with a force of 100N and Anne can pull woth a force of 30N. Determine if the different configurations of teams are balanced or unbalanced. write the configuration of teams in the correct row.
Balanced
Unbalanced
- Tim versus Elena and Anne
- Elena versus Tim and Anne
- Anne versus Tim and Elena
Answer:
- Tim versus Elena and Anne: unbalanced
- Elena versus Tim and Anne: balanced
- Anne versus Tim and Elena: unbalanced
Explanation: In a game of tug of war, the opposing teams pull the rope in opposite direction. If there is <u>equilibrium</u> in the forces, i.e., the opposing forces are <u>balanced</u> and the force resultant is 0, there is no winner.
If the pulling force of one side is <u>bigger</u> than the other, i.e., if there is a desequilibrium, the opposing forces are <u>unbalanced</u> and whichever is greater wins the game.
In the cases described, suppose the positive direction is towards the right side.
1) <u>Tim x Elena and Anne</u>: there is no equilibrium because the force Tim pulls is smaller than Elena and Anne combined and so, the forces are <u>unbalanced</u>.
Force = 70 + (-100-30)
Force = -60N
2) <u>Elena x Tim and Anne</u>: Here the forces result in equilibrium, so they are <em><u>balanced</u></em>.
Force = 100 + (-70-30)
Force = 0
3) <u>Anne x Tim and Elena</u>: Force of one side is greater than the other. So, there is no equilibrium and so, the forces are <em><u>unbalanced</u></em>.
Force = 30 + (-100-70)
Force = -140N
