Calculate the upthrust on a spherical ball of volume 4.2 x 10\(^{-4}\)m\(^{3}\) when totally immersed in a liquid of density 1028kgm\(^{-3}\)
- 5.2N
-
4.3N
- 3.0N
- 2.4N
The correct answer is: B
Explanation
Upthrust(Force) = volume of object x density of liquid x g = V x \(\rho\) x g
U = 4.2 x 10\(^{-4}\) x 1028 x 10 \(\approxeq\) 4.3N
