Fluid statics question?
XanX asked:
An iron anchor appears 20,000 N lighter in water than in air.
An iron anchor appears 20,000 N lighter in water than in air.
What is the volume of the anchor?
How much does it weigh in air?
I think i got the volum right at .127m^3, but Im unsure how to solve for the weight in air, and Im hoping to get confirmation on the volume, thanks for your help.

F_archimedes = ?_water g V = 1000 (9.8) V = 20000
V = 2.0408163 m³
W_air = ?_iron g V = (7870)(9.8)(2.0408163)
W_air = 157.4 kN
This is an arctlie that makes you think \”never thought of that!\”
