Answer:
3.85 percent
Explanation:
From the question,
Percentage error = (error/actual)×100................ Equation 1
Given: actual center of mass = 15 cm, error = 15.6-15 = 0.6 cm
Substitute these values into equation 1
Percentage error = (0.6/15.6)×100
Percentage error = 3.85 percent
Hence the percentage error of the uniform mass = 3.85 percent
All of the above but normally in a triple beam
