The lengths of two cylindrical rods are measured as

\ell_1=(5.62 \pm 0.01) \mathrm{cm}

and

\ell_2=(4.34 \pm 0.02) \mathrm{cm}

. What is maximum percentage error in measurement of difference of lengths of two cylinders?

View answer and explanation

Correct option: B

2.34 \%

Option B (

2.34 \%

) is correct because it is the maximum percentage error calculated by adding the absolute errors and dividing by the difference in lengths.
