Question

The gravitational force exerted on a solid object is 5.05 N as measured when the object is suspended from a spring scale as in Figure (a). When the suspended object is submerged in water, the scale reads 3.04 N (Figure (b)). Find the density of the object.

The gravitational force exerted on a solid object is 5.05 N as measured when the object is suspended from a spring scale as in Figure (a). When the suspended object is submerged in water, the scale reads 3.04 N (Figure (b)). Find the density of the object.

Explanation / Answer

B = M g - T2 = 5.05 - 3.04 = 2.01 N

==> rho = 2.51 x 10^3 Kg/m3
