Individual measurements introduce errors that may be large or small depending on the quality of the tools and processes used. Sc

kirill [66]

Answer:

B. accepted value x 0.1

Explanation:

in the equation provided

$Percentage Error=\frac{Error}{AcceptedValue} X100$

Maximum allowed value of percentage error = 10%

put this value in the equation in stead of percentage error we get,

$10 = \frac{error}{AcceptedValue} X100\\ \frac{10}{100} =\frac{error}{AcceptedValue}\\.1=\frac{error}{AcceptedValue}\\error = .1 X Accepted Value$

so maximum error = .1 x accepted value

10 % percentage error means the experimental value has 10 % error compared to accepted value.so error will be 10 % of the accepted value

or .1 times of accepted value
