Correct Answer: Option B
Explanation:
% error = \(\frac{\text{actual error}}{\text{true value}}\) x 100
Where actual error = 5.1 - 5.0 = 0.1
true value = 5.0g
% error = \(\frac{0.1}{5.0}\) x 100
= \(\frac{10}{5}\)
= 2%
% error = \(\frac{\text{actual error}}{\text{true value}}\) x 100
Where actual error = 5.1 - 5.0 = 0.1
true value = 5.0g
% error = \(\frac{0.1}{5.0}\) x 100
= \(\frac{10}{5}\)
= 2%
