The accepted value of a length measurement is 200 cm, and the experimental value is

198cm. Calculate the percent error.

-1%

Percent error = - 1%

Explanation:

Given dа ta:

Accepted value = 200 cm

Experimental value = 198 cm

Percent error = ?

Solution:

Formula:

Percent error = [Experimental value - accepted value / accepted value]*100

Now we will put the values:

Percent error = [198 cm - 200 cm / 200 cm] * 100

Percent error = - 0.01*100

Percent error = - 1%
