What buoyant force is experienced by an object that is partially immersed in a liquid of density 920 kg m\(^{−3}\) and displacing 4.5 × 10\(^{−2}\) m\(^3\) of the volume of it?
A
217 N
B
48 N
C
414 N
D
360 N
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Given: \(\rho\) = 920 kg m\(^{−3}\), g = 10m/s\(^2\), V = 4.5 × 10\(^{−2}\) m\(^3\)
But, F\(_b\) = V\(\rho\)g = 4.5 × 10\(^{−2}\) x 920 x 10 = 414N
