Fluida Statis
• Hk Archimedes
mb = 100 gr = 0,1 kg [b = bola]
r = 5 cm = 5×10^-2 m
ρ = 1000 kg/m³
mt = ___? [t = timah hitam]
Volume bola
V = (4/3) π r³
V = (4/3) π (5×10^-2)³
V = π/6000 m³
Pada saat tepat seluruh bola tercelup, gaya berat bola+isi = gaya apung.
(mb + mt) g = ρ g V
(0,1 + mt) = (1000) (π/6000)
0,1 + mt = π/6
mt = (π/6 – 0,1) kg
mt = 423,6 gram ←
