Two parallel, but not necessarily unidirectional, forces of magnitude 1 N and 2 N are acting on a body. Two more, parallel, again not necessarily unidirectional, forces of magnitude 3 N and 1 N, but perpendicular to the earlier forces, are applied to the body. Which one among the following are the smallest and largest possible magnitudes of the resultant force on the body?
