Discuss the below:
Q: When two vectors A and B are drawn from a common point, the angle between them is (phi) .
If A and B have the same magnitude, for which value of (phi) will their vector sum have the same magnitude as A or B?
Three horizontal ropes pull on a large stone stuck in the ground, producing the vector forces A, B, and C shown in the figure
(a) Find the magnitude of a fourth force on the stone that will make the vector sum of the four forces zero. I dont know how to set up this problem.
(b) Find the direction of a fourth force on the stone that will make the vector sum of the four forces zero.(counterclockwise from positive x-axis.
