Calculate the upthrust on a spherical ball of volume 4.2x10+ m³ when totally immersed in a liquid of density
1028 kgm³
(g=10 ms²)
(A)
3.0 N
(B)
4.3 N
5.2 N
(D)
2.4 N



Answer :

To calculate the upthrust on a spherical ball immersed in a liquid, you can use the formula: Upthrust = Volume of the ball × Density of the liquid × Acceleration due to gravity Given: - Volume of the spherical ball = 4.2 x 10^-3 m³ - Density of the liquid = 1028 kg/m³ - Acceleration due to gravity (g) = 10 m/s² Now, plug in the values into the formula: Upthrust = 4.2 x 10^-3 m³ × 1028 kg/m³ × 10 m/s² Upthrust = 4.2 x 10^-3 × 1028 × 10 N Upthrust = 43.056 N Therefore, the upthrust on the spherical ball of volume 4.2 x 10^-3 m³ when totally immersed in the liquid is approximately 43.056 N. So, the closest option to the calculated value is: (B) 43.1 N
