Answer:
Percentage error, P % = 4.16 %
Explanation:
Given that,
Actual value of the mass of an object, m = 250 g
Observed value of the mass, m' = 240 g
We need to find the percentage error in the mass of the object. It is given by :
[tex]P\%=|\dfrac{m'-m}{m}|\times 100[/tex]
[tex]P\%=|\dfrac{240-250}{250}|\times 100[/tex]
[tex]P\%=4\%[/tex]
So, the percentage error in the calculated value is 4%. Hence, this is the required solution.
