The following equipment is available: a solid metal block, a spring dynamometer, thin wire, a large beaker, and an appropriate amount of water, The density of water is known, 2 letter expression of metal block density=

The following equipment is available: a solid metal block, a spring dynamometer, thin wire, a large beaker, and an appropriate amount of water, The density of water is known, 2 letter expression of metal block density=

1. The weight g in air is measured by spring dynamometer
2. Suspend the metal block in the water and read the indication F of the spring dynamometer
ρ = ρ water g / (G-F)
For reference only!

Please measure the density of a small stone with a spring dynamometer beaker
