1. The buoyant force component is in the inward radial direction. 2. When the buoyant force equals 1 ton, it will sink no farther. 3. Gravity pulls it down and water pressure / buoyant force pushes it up. 4. The buoyant force , which always opposes gravity, is nevertheless caused by gravity. 5. Using \ rho _ f for the density of the fluid, the buoyant force is: 6. Other second order processes include tidal and seismic events, buoyant forces and melt water wedging. 7. The lift capability of an airship is equal to the buoyant force minus the weight of the airship. 8. The weight of the displaced portion of the fluid is equivalent to the magnitude of the buoyant force . 9. Since buoyant force points upwards, in the direction opposite to gravity, then pressure in the fluid increases downwards. 10. Now the question is whether the resulting density of helium is sufficiently low to provide 200 pounds of buoyant force .
