A sphere of mass 5 kg and volume 2.2×10−4 m3 is completely immersed in water. Find the buoyant force exerted by water on the sphere. Density of water =1000 kg-m−3 and take g=10 m/s2

The correct option is B 2.2 NBuoyant force exerted by water on the sphere, F=ρgV ⇒F=1000×10×2.2×10−4=2.2 N Hence, option (B) is the correct answer.

A sphere of mass $5 kg$ and volume $2.2 \times 10^{- 4} m^{3}$ is completely immersed in water. Find the buoyant force exerted by water on the sphere.

Density of water $= 1000 {kg-m}^{- 3}$ and take $g = 10 {m/s}^{2}$

The correct option is B $2.2 N$
Buoyant force exerted by water on the sphere,

$F = ρ g V$

$\Rightarrow F = 1000 \times 10 \times 2.2 \times 10^{- 4} = 2.2 N$

Hence, option $(B)$ is the correct answer.
