Question 2 of 2 Incorrect sapling learning e meter stick shown to the right is 00 cm long. It is free to pivot around its center of gravity (CG), which is at 10 20 30 40 50 60 70 the 50-cm mark. There is a 25.0-N block hanging from the 80-cm mark. Decide where each of the other blocks should be placed, one at a time, to balance out the 25.0-N block. 25.0 N 16.0 N At what mark on the meter stick 44.0 N would you place a 16.0-N block to balance the 25.0-N block? Incorrect. Number 46.9 cm is the length of the lever arm, but that is how far the block should be placed from the pivot point (which is 46.87 located at the CG) rather than the actual ruler marking. If cmn the 16.0-N block is placed 46.9 cm from the pivot, where on the ruler will that be? At what mark on the meter stick would you place a 44.0-N block to balance the 25.0-N block? Number 3.13 cmi 90
