The diagram shows two forces acting on an object.They have magnitudes F1=3.2N and F2=9.6 N.What third force will cause the object to be in equilibrium? https://tcan4424-oakcliff-ccl.gradpoint.com/Resour...

20The diagram shows two forces acting perpendicularly on an object. The forces have magnitudes F1 = 8.2 N and F2 = 20.6 N. https://tcan4424-oakcliff-ccl.gradpoint.com/Resour...

The opposite equivalent force is found by:

F=sqrt(3.2^2+9.6^2)=10.12N

It makes the following angle with the negative of the "1" axis (the axis of F1): tan^(-1)(9.6/3.2)=71.56 degrees or 180+71.56 degrees = 251.56 degrees with the positive "1" axis (same thing) It lies in the 3rd quadrant


20. I am assuming you ask here the same question. The answer is :

The opposite equivalent force is found by:

F=sqrt(8.2^2+20.6^2)=22.17N

It makes the following angle with the negative of the "1" axis (the axis of F1): tan^(-1)(20.6/8.2)=68.29 degrees or 180+68.29 degrees = 248.29 degrees with the positive "1" axis (same thing). It lies in the 3rd quadrant
