Question

Consider the diagram below. Note: The r values are distances measured from the wedge. The x values are measured from the end of the meter stick. Suppose you have numerical values for x0 - the position of the fulcrum Xm - the position of the mass rm - the distance from the fulcrum to the mass rs - the distance from the fulcrum to the center of mass of the meter stick What would be the simplest combination of these values that can be used to determine the position of the center of mass of the stick, Xs?

Explanation / Answer

The center of mass of the stick will be at its geometrical center

so Xs= Xo+rs . so the option (a) is correct.
