Fnet = Fb - Fg since Fnet is the net force
Plugging into the first equation above, with object volume V and gravity g: Fb - Fg = (pf - p0) * V * g Dividing both sides by Fg = p0 * V * g (Fb - Fg) / Fg = (pf - p0) * V * g / Fg (Fb - Fg) / Fg = (pf - p0) * V * g / (p0 * V * g) Fb/Fg - 1 = pf / p0 - 1 Fb/Fg = pf / p0 Done, although both sides need to be flipped Ads |
