A uniform rod $AB$ is suspended from a point $X$, at a variable distance $x$ from $A$, as shown. To make the rod horizontal, a mass $m$ is suspended from its end $A$. A set of $(m, x)$ value is recorded. The appropriate variables that give a straight line, when plotted, are:

1. $m,x^2$
2. $m,\frac{1}{x^2}$
3. $m,\frac{1}{x}$
4. $m,x$
