A) 1
B) 2
C) 3
D) 4
Correct Answer: D
Solution :
[d] Density, \[\rho =\frac{M}{V}=\frac{M}{\pi {{r}^{2}}\ell }\] \[\therefore \,\,\,\frac{\Delta \rho }{\rho }\times 100=\left[ \frac{\Delta M}{M}+\frac{2\Delta r}{r}+\frac{\Delta \ell }{\ell } \right]\times 100=4\]You need to login to perform this action.
