CBSE Class 11-science Answered
Two different masses are determined as ( 23.7 ± 0.5 ) g and ( 17.6 ± 0.3 ) g . What is the sum of their masses?

Expert Answer
Δm1 = 0.5
Δm2 = 0.3
maximum absolute value of error in mass
Δz = 
(m1 + Δm2)
(m1 + Δm2)Thus,
Δz = ( 23.7 + 17.6 ) (0.5 +0.3) = (41.3 0.8)g
(0.5 +0.3) = (41.3 0.8)g
