Answer:
6.67 %
Explanation:
Given that,
Measured height of a small lamp, l = 32 cm
Actual height, l' = 30 cm
We need to find the percent error of the student's measurement. Percent error is given by :
[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]
Putting all the values, we get :
[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]
So, the percent error of the student's measurement is 6.67 %.
