Thread: Need help with this forces question

A particle is acted upon by the following four forces: 25 N pulling east, 30 N pulling west, 54 N pulling north and 42 N pulling south.

Calculate the resultant and equilibrant of these forces.

I don't know how to solve it, please help me a little, thanks.

let east/west be the x-direction ...

25N - 30N = -5N ... west component

north/south be the y-direction ...

54N - 42N = 12N ... north component

resultant magnitude,

resultant direction, counter-clockwise from east (the +x-axis), or north of west.

If is the resultant vector, then is the equilibrant vector.
