Question

the length of the body 3.51 m, if the accuracy measured as 0.01mm then percentage error in the measurement is?

Answer 1

The length of a body , L = 3.51 m
And accuracy of its length , ∆L = 0.01 mm = 0.01 × 10⁻³ m = 10⁻⁵ m
we know , % error = relative error × 100
or , % error in Length = ∆L/L × 100

Now, % error in Length = 10⁻⁵/3.51 × 100
= 10⁻³/3.51 = 1/3510
= 0.000284

I think question should be given accuracy 0.01m not 0.01mm
well, rule is the % error = relative error × 100

if ∆L = 0.01m and L = 3.51
Then, % error in measurement = 0.01/3.51 × 100 = 1/3.51 = 0.28 %
