Question

Three forces act on a point: 3 N east, 4 N at north, and 5 N at 37° south of west. What is the net force?

Answer 1

If the forces can be made to cancel the resultant would be zero,this means that the diagram would look like a triangle. So the question becomes,can these three vectors be arranged to form a triangle?The answer is yes,I know that a traingle with sides 3,4,5 units of length is a right angle triangle. So the answer is zero.

i hope this helps:)!
