A wire has a mass `(0.3+-0.003)g`, radius `(0.5+-0.005)mm` and length `(6+-0.06)cm`. The maximum percentage error in the measurement of its density is

A

3

B

4

C

6

D

`-2`

Text Solution

Verified by Experts

The correct Answer is:
B
`%`error in density `=[2((0.005 )/(0.5 ))+(0.003)/(0.3 ) +(0.06)/(6)]xx 100 =4`
