Answer:
3: 1
Explanation:
When the solid is in air the force acting on it is only its actual weight = Mg
Mg= Vdg
M= mass
v= volume
d=density of solid
g= gravitational acceleration
When in kerosene It's weight and an upthrist acts on it
So what we measure as the apparent weight in kerosene is the difference between its weight and the upthrust
W = weight in kerosene
W= Mg-Vdkg
dk= density of kerosene
Vdkg= Mg - W
d:dk = Vdg: Vdkg
= 4.8 : 4.8-3.2
=4.8: 1.6
=3:1
