A steel block has a volume of 0.08 m³ and a density of 7,840 kg/m³. What is the force of gravity acting
on the block (the weight) in water?

Respuesta :

Mass of water displaced = (0.08 x 1000) = 80kg. (Density of water = 1000kg/m^3).
Mass of steel block in air = (7840 x0 .08) = 627.2kg.
Difference = (627.2 - 80) = 592.2kg.
592.2 x 9.8 = 5,803.56N. apparent weight when immersed in the water.
