Which of the four arrangements in the figure correctly shows the vector addition of two forces `vecF_(1)` and `vecF_(2)` to yield the third force `vecF_(3)`

Which of the figure's six arrangements correctly show the vector addition of forces vec(F)_(1) and vec(F)_(2) to yield the third vector, which is meant to represent their net force vec(F)_("net") ?

The resultant of the forces vecF_(1)=4hati-3hatj and vecF_(2)=6hati+8hatj is

The resultant of the forces vecF_(1) = 4hati-3hatj and vecF_(2) = 6hati + 8hatj is

The resultant of the forces vecF_(1) = 4hati-3hatj and vecF_(2) = 6hati + 8hatj is

A body is at rest under the action of three forces, two of which are vecF_(1)=4hati, vecF_(2)=6hatj , the third force is

The figure shows an overhead view of a meter stick that can pivot about the point indicated, which is to the left of the stick's midpoint. Two horizontal forces, vecF_(1)andvecF_(2) , are applied to the stick. Only vecF_(1) is shown. Force vecF_(2) is perpendicular to the stick and is applied at the right end. If the stick is not to turn, (a) what should be the direction of vecF_(2) , and (b) should F_(2) be greater than, less than, or equal to F_(1) ?
