Question

Mass of a body is measured as 7.5 kg + - 2% then absolute error in measurement of mass is

Answer 1

Mass of a body is measured as 7.5 kg + - 2% then absolute error in measurement of mass is..

answer : 0.15 Kg

explanation: Mass of a body is measured as (7.5Kg ± 2%)

we have to find absolute error.

absolute error is the amount of error our measurements. it is the difference between actual value to measure value.

for here, absolute error = 2% of 7.5 Kg

= 2/100 × 7.5 Kg

= 15/100

= 0.15 Kg

hence, absolute error in measurement of mass is 0.15 kg.
