Question
We have error in the measurement of length, radius, mass and current of a wire are $2 \%, 3 \%, 2 \%$ and $1 \%$ then error in its density will be(A) $11 \%$(B) $8 \%$(C) $10 \%$(D) $7 \%$
Step 1
The density (Ļ) of a wire is given by the formula: \[Ļ = \frac{m}{Ļr^2l}\] where m is the mass, r is the radius, and l is the length of the wire. Show more…

. We have error in the measurement of length, radius, mass and current of a wire are 2%, 3%, 2% and 1% then error in its density will be
A wire is of mass $(0.3 \pm 0.003) \mathrm{gm}$. The radius is $(0.5 \pm 0.005) \mathrm{mm}$ and length is $(6.0 \pm 0.06) \mathrm{cm}$ then $\%$ error in density is (A) 3 (B) 4 (C) 6 (D) $-2$
A wire is of mass (0.3 Ā± 0.003) gm. The radius is (0.5 Ā± 0.005)mm and length is (6.0 Ā± 0.06) cm then % error in density is
