Hi! So I am really stuck right now. I cannot seem to get the experimental weight of the meter stick correct. I was told by someone else who did this lab that the percent error is the same, but I keep getting two different answers because the experimental weight of the meter stick is in correct. Can anyone help? I included the other portion to show how I got the other percent error. I'm pretty sure everything else is correct, but then again I'm not 100% confident. All I really need help with is the experimental weight of the meter stick. Thank you!

The following procedure from the lab worksheet has been performed for you to capture the required data. Use the data provided to calculate the unknowns. 1. Clamp the knife-edge to the 30-cm mark of the meter stick. 2. Place 400 grams at the 25-cm mark (use this as r), and put a ZOO-gram weight to the opposite side of the fulcrum, so as to make the loaded meter stick balance horizontally. 3. The true value of the weight of the meter stick (by using the triple beam balance) is 140.5 grams. 4. Calculate the difference between the two torque values: 0-27 Nm 5. Calculate the Experimental Value of the Meter Stick: 93 g HINT: rlml = rxmX + r2m2 NOTE: You must use the indicated units in your answers or you will be marked wrong. The following procedure from the lab worksheet has been performed for you to capture the required data. Use the data provided to calculate the unknowns. 1. Support the meter stick at the center of gravity. Hang the unknown weight at the 70-cm mark as rx, and balance with suitable known weight (as m1) on the other side (as r1} of the fulcrum. 2. Weigh the unknown mass on the balance to get the true value. The true value of the unknown weight is 375 grams. 3. Calculate the Experimental Value of the Unknown Weight: 381 g HINT: rxmX = r1m1 NOTE: You must use the indicated units in your answers or you will be marked wrong. CALCULATE PERCENTAGE OF ERROR Calculate the Percentage of Error using the following relationships. Use the True Value for the Meter Stick and the Experimental Value you calculated for the Meter Stick from the second procedure.
