Question

density of a body is two fifth of density of water find the R.D. of the body​

Answer 1

Explanation:

IB Boyand Force

Mg−IB=32Mg

31MgB=FB...(i)

M=s×p×v×g

s is specific gravity

31×s×p×v×g=2.6×p×v×g

S=7.8

Now,

Density of waterDensity of material=Relative Density

Density of material=7.8×1000

=7.8×1000×kg/m3.
