A solid sphere of radius 5 cm floats in water. If a maximum load of 0.1 kg can be put on it without wetting the load, find the specific gravity of the material of the sphere

Dear Student, 

Mg +mg = Vρg
M+m=Vρ
M+0.1=4π0.053×1033as volume of sphere = volume of system under waterM=0.4233
density of the sphere is 
ρs=0.42330.5233=0.808=0.81 kg m-3

Regards
