A metallic sphere of 4kg and volume 2.5×10^-4 m^3 is half submerged i

1.	A metallic sphere of 4kg and volume 2.5×10^-4 m^3 is half submerged in water. Find the buoyant force exerted by water on the sphere. Density of water= 1000kg/m^3.
Answer» Answer: EXPLANATION: Mass of ball m = 4 kg Density of ball ρ = 4000 kg/m3 VOLUME of the ball V = m/ρ = 4/4000 m3 = 10-3 m3. Buoyant FORCE or upthrust acting on the ball = Volume of water displaced x density of water x acceleration DUE to gravity = 10-3 m3 x 1000 kg/m3 x 9.8 m/s2 = 9.8 kg. m/s2 = 9.8 N.

Answer»

Answer:

Mass of ball m = 4 kg Density of ball ρ = 4000 kg/m3 VOLUME of the ball V = m/ρ = 4/4000 m3 = 10-3 m3.

Buoyant FORCE or upthrust acting on the ball = Volume of water displaced x density of water x acceleration DUE to gravity

= 10-3 m3 x 1000 kg/m3 x 9.8 m/s2 = 9.8 kg. m/s2 = 9.8 N.
