QUESTION 2 2 points Save Answer Consider the diagram below of a seesaw of length L with two blocks fixed onto it as shown. The vertical dashed line marks the center of the seesaw as well as the midpoint (L' L/2) to the two blocks. Assume the larger box (located at L' = 0) has twice the mass of the smaller box (located at L' = L). Approximately, where would you position the wedge such that the seesaw would be balanced i.e., choose the letter that corresponds to the correct position on the wedge)? Note: this position on the wedge is given by L' in terms of the total length L of the wedge B. B: L' L/4 0 D. D: L' = 3L/4

Explanation / Answer

Center of mass of the two wedges:

COM = (2M*0 + M*L)/(2M+M)

= ML/(3M)

= L/3

As the center of mass of the two wedges is located at L/3 distance from the leftmost point,

So, the correct option is B) L/4
