Question

A piece of material x is given to us mass 40g and its volume is 10cm³ with error in limits of 1cm³ find density

Answer 1

Hey Dear,

◆ Answer -

Density = 4±0.4 g/cm³

◆ Explanation -

# Given -

M = 40 g

V = 10 cm³

∆V = 1 cm³

# Solution -

Mean density of given material will be -

d = M / V

d = 40 / 10

d = 4 g/cm³

Error in measurement of mass is not given. So we'll just have to assume it as zero. i.e. ∆M = 0 g.

Relative error in measurement of density will thus be -

∆d/d = ∆M/M + ∆V/V

∆d/4 = 0/40 + 1/10

∆d = 4 × 1/10

∆d = 0.4 g/cm³

Therefore, density of the material can be given as 4±0.4 g/cm³.

Thanks dear...
