The error in the measurement of length and mass of a cube is 3% and 4% respectively. The error in the measurement of its density will be

Show answer and solution

Answer: (a)

  1. ρ=mL3⇒Δρρ=Δmm+3ΔLL\rho = \frac{m}{L^{3}} \Rightarrow \frac{\Delta\rho}{\rho} = \frac{\Delta m}{m} + 3\frac{\Delta L}{L}
  2. =4%+3×3%=13%= 4\% + 3 \times 3\% = 13\%
  3. So the answer is (a) 13%13\%.
