Q: The relative density of a metal may be found by hanging a block of the metal from a spring balance and noting that in air, the balance reads ( 5.00 ± 0.05) N, while in water it reads ( 4.00 ± 0.05) N. the relative density would be quoted as
(a) 5.00 ± 0.05
(b) 5.00 ± 0.10
(c) 5.00 ± 6%
(d) 5.00 ± 11%
