HELP!! Physics question on bouancy force!?
While gravity pulls the ship down, buoyant force pushes it upRemember the sum of the forces: Fnet Tension(up) + Buoyant force(up) - mg(down) 0 So rearranging: Tension mg - Buoyant force Buoyant force weight of the water displaced Don't know what volumes to use? Remember you can get volume by: Density mass/volume so mass/Density volume Volume of the steel ship underwater is the volume of water displacedBut you knew this already didn't you?
