The equilibrant of a force is the force which is equal and opposite to that force. If two forces are equal and opposite, their x and y components are also equal, but the x and y components of the force are opposite in sign to those of the equilibrant.
The x and y components of a force are 2 Newtons and 3 Newtons repectively.
• What are the magnitude of this force and what angle does it make as measured counterclockwise from the positive x axis?
F=’sqrt(3 N^2 + 2N^2) = ‘sqrt(13) = 3.6 N
Arctan(3N/2N) = 56.3 deg.

• What angle does the equilibrant force make as measured counterclockwise from the positive x axis?
Arctan(-3N/-2N) + 180 = 236.3 deg.
