Two forces P and Q act on an object.
Which diagram shows the resultant of these two forces?

The diagram that shows the resultant of two forces P and Q on an object represented by vector lines is;
Option C
We are told that the forces P and Q act on an object.
Now since they act on an object, it means the point of the object will be where both P and Q meet each other.
Looking at the given options, we see that the only one that fits our definition above about the resultant of 2D vector lines is Option C.
