The gravitational force exerted on a solid object is 5.70 N. When the object is suspended from a spring scale and submerged in water, the scale reads 2.10 N (figure). Find the density of the object.

Solutions

Expert Solution

Gravitational acceleration = g = 9.81 m/s²

Density of water = _w = 1000 kg/m³

Density of the object =

Weight of the object = W = 5.7 N

Volume of the object = V

Reading of the scale when the object in when submerged in water = W_a = 2.1 N

Buoyancy force on the object when it is submerged in water = F_b

The actual weight of the object is supported by the buoyancy force on it and the force the scale exerts on the object.

= 1583.3 kg/m³

Density of the object = 1583.3 kg/m³
