A solid sphere of radius R has a concwntric circle of radius R/2 inside it. The sphere is found to just float in water with the highest point of it touching the wtarer surface . The specific gravity of the material of the sphere is______

Question

Arun · Answer

Upward trust of the water to the solid sphere= 3 4 ​ πR 3 ×1×g Now, for equilibrium, upward trust = weight of the solid = 3 4 ​ π(R 3 − 8 R 3 ​ )d×g= 3 4 ​ πR 3 g d solid ​ = (1− 8 1 ​ ) 1 ​ = 7 8 ​ ∴ specific gravity of the material= d vater ​ d solid ​ ​ = 7 8 ​
