Question

Given values: m1=10 kg, r1=75 cm, m3=15 kg, had to find r3=? I got r3=50cm

m1 = 10 kg at r1 = 75 cm

m3 = 15 kg at r3 = 50 cm

1. compute the theoretical value of r3 using the equation:

r1m1 = r3m3

2. compute the % error of r3 using the following equation:

% error = |theoretical value - experimental value| / theoretical value x100%?

(r3 theoretical = r1 - m1 / m3 x 100%)

Case 1-Two Known Masses: 1) Place a mass m1 = 10 kg at 75 cm to the left of the center of the rod. 2) Click the switch to remove the stands 3) Place a mass m3 = 15 kg to the right of the center of the rod. Adjust the placement of the mass until the ruler balances. 4) When the ruler balances, record the location of the mass as the experimental value of r3 5) Compute the theoretical value of r3 using the equation: ri m1 13 m3 6) Compute the % error of r3 using the following equation: |Theoretical Value - Experimental Value| % Error %D X 100% Theoretical Value
