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, then the density of the material of
the sphere is (Density of water = 1000 kg m-3)
A 960 kg m-3
B 900 kg m-3
C 850 kg m-3
D 800 kg m-3
How to solve this

Class : Class 9
Volume of the solid cube =(25*25*25)/1000000 cubic metre.
Mass of the solid cube = the mass of the body which can be placed on it to completely submerge it
Density = 0.1kg/ 125*(10)^6=800kg/m^3
