In the following example, we have omitted some beginning and ending material that is standard HTML. See the section showing the complete source file template for more information. We do show all the material between the <QUESTION...> and </QUESTION> tags.
First, we indicate the type of question and give the text of the question itself.
<QUESTION TYPE=True-False> Two forces of equal magnitude, <VAR>F</VAR>, act on a body of point size. The forces have the same line of action but are in opposite directions. The magnitude of the vector sum of these forces is therefore <VAR>0</VAR>.
<ANSWER ANS=true> <RESPONSES> <WHEN INCORRECT> Remember that, because the forces are in opposite directions (the angle between them is 180 degrees), the magnitude of one is the negative of the magnitude of the other. </RESPONSES>
We just end the question with:
