The forces each of 20N act on a body at 120^(@) The magnitude and direction of resultant is

A force F _(1), of magnitude 2.0N and directed due east is exerted on an object. A second force exerted on the object is F _(2)=2. 0 N, due north. Wha tis the magnitude and direction of a third force, F _(3), which must be exerted on the object so that the resultant force is zero ?
