What is the net force in this question?

Click For Summary

Homework Help Overview

The discussion revolves around determining the net force in a scenario involving forces acting in different directions. The original poster expresses uncertainty about the correct approach to calculate the net force, particularly when forces may be acting in opposing or different directions.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster considers whether the net force could be 12N or 0N and questions whether to add or subtract forces acting in different directions. Some participants suggest conducting experiments to observe the effects of pulling forces, while others mention using vector addition to clarify resultant forces.

Discussion Status

The discussion includes various perspectives on how to approach the problem, with participants offering different methods for visualizing and calculating the net force. There is no explicit consensus, but several productive suggestions have been made regarding experimental approaches and vector addition.

Contextual Notes

The original poster indicates a lack of certainty due to missing class and seeks clarification on the problem setup. The discussion also hints at the complexity of forces not acting directly opposite to each other.

Homework Statement


I need to find the net force of the following, I am pretty sure i know the answer, but i just wanted to check to see if i am actually doing it correctly


Homework Equations


i just need to find the net force (i have attached the question)


The Attempt at a Solution


Would the net force be 12N or 0N
I get how to work it out the netforce when there are forces working in opposite directions, but i wasnt to sure if i am meant to add or subtract when going in different direction

Ask you friend to help you doing an experiment.
Both of you pull the object as in your problem configuration with equal force/pull for 10sec.
Find the track the object made.

2nd experiment.
Next you alone pull southerly for say 10 sec.
Then ask you friend to pull westerly for another 10 sec.
Check the final location of the object.

If the forces are not in opposite directions, the best way to make it clear what the resultant force would look like is to add the vectors head to tail. Here the forces are at right angles to one another so a quick application of Pythagoras will give you the resultant force (which will point towards bottom left )
 
Thank you all so much for your help! i was away in class today and i wasnt 100% sure :)
