Question

A metallic sphere of radius 2.0 cm is completely inmersed in water. find the force of buoyancy on it.
​

Answer 1

Hey !

______

Given,

Radius of the sphere = 2 cm = 0.02 m

Volume of the solid sphere = 4/3×π× (r)^3

= 4/3 × 3.14 × (0.02)^3

= 33.5 × 10^-6 m^3

Now,

Force of buoyancy = density of water × volume immersed × acceleration due to gravity

F = ( 1000 × 33.5 × 10^-6 × 9.8 ) N

Therefore , F = 0.33 N
