The density of the material of cylindrical rod was determined by the formula d = m/π r2 l. The percentage error in m, r and l are 3%, 2% and 0.8% respectively. Calculate the maximum possible percentage error in determination of density​

Answer:

Explanation:

Given,

Δm/m X 100 = 3

Δr/r X 100 = 2

Δl/l X 100 = 0.8

Maximum percentage error,

Δd/d X 100 = Δm/m X 100 + 2Δr/r X 100  + Δl/l X 100

                    = 3 + 2(2) + 0.8

                    = 7.8%
