Question
Given values: m1 = 10kg, r1=75 cm, m3=20kg, r3=25cm, m4=5kg, had to find the value of r4=? I got r4=50cm
m1 = 10 kg at r1 = 75cm
m3 = 20 kg at r3 = 25cm
m4 = 5 kg at r4 = 50cm
1. Compute the theoretical value of r3 using the following equation:
r1m1 = r3m3 + r4m4
2. Compute the % error of r3 using the following equation:
% error = |theoretical value - experimental value| / theoretical value x 100%
Transcribed Image Text:1) Place a mass m1
10 kg at r, = 75 cm to the left of the center of the rod.
2) Click the switch to remove the stands
3) Place a mass m3
20 kg at r3 = 25 cm to the right of the center of the rod. Adjust the
%3D
placement of the mass until the ruler balances.
4) Place a mass m, = 5 kg to the right of the center of the rod. Adjust the placement of
the mass until the ruler balances.
5) When the ruler balances, record the location of the mass as the experimental value of r.
6) Compute the theoretical value of r3 using the equation:
T3 m3
7) Compute the % error of rz using the following equation:
|Theoretical Value - Experimental Value|
Theoretical Value
