An object acted on by three forces moves with constant velocity. one force acting on the object is in the positive x direction and has magnitude of 6.5 N, a second force has a magnitude of 4.4 N and points in the negative direction. Find the direction and magnitude of the third force acting on the object.

total Fx = 0 if no acceleration

6.5 - 4.4 + x = 0
2.1 + x = 0
x = -2.1 N
