The accepted value of a length measurement is 200cm, and the experimental value is 198cm. Circle the letter of the value that shows the precent error of this measuerment.
a)2%
b)2%
c)1%
d)1%
is it b)2%
No. What is 2/200 * 100?
Percent error = deviation/GAAT * 100
gAAT generally accepted as true. Now watch signs...deviation = measured  GAAT

200cm= 2
