A model See$-$Saw can be built by drilling a hole through the center of mass of a meter stick and balancing the meter stick on a horizontal rod inserted through the hole.

First, the model See$-$Saw is balanced with no weights on it$.$ Then, a small weight will be placed relatively far from the center, at the $10$ cm mark. Where should the other, larger weight be placed in order to balance the See$-$Saw? Write your answer and an explanation of the reasoning on your whiteboard. The discussion should lead to a result with which all can agree. After the class has agreed on an explanation, record that explanation. $q,$
