A wire has a mass `(0.3pm0.003)`g, radius `(0.5pm0.005)` mm and length `(0.6pm0.006)` cm. The maximum percentage error in the measurement of its density

Explanation

density `rho=("mass")/("volume")=m/(pir^(2)l)`
`:.` percentage errors in `rho=(Deltam)/mxx100+2(Deltar)/rxx100+(Deltal)/lxx100`
`=0.003/0.3xx100+2xx0.005/0.5xx100+0.06/6xx100=4%`
