Two coplanar forces act on an object as shown. [Figure showing two forces originating from an object, one pointing up-right and another pointing right] Which diagram shows the resultant F of these two forces?
ADiagram showing a resultant F vector by placing the tail of the second force at the head of the first force, and then drawing F from the tail of the first to the head of the second.
BDiagram showing a resultant F vector formed by drawing F from the tail of the first force to the tip of one of the forces.
CDiagram showing a resultant F vector by using the parallelogram rule but pointing in the opposite direction (down-left).
DDiagram showing a resultant F vector by using the parallelogram rule, pointing in the correct (up-right) direction.
