It will move upward linearly B_1, B_2 from It will move upward linearly. Forces exerted By water only. Vertical forces are B_4, B_3 B_3 > B_4 Bottom surfaces is more depth than upper, hence force of Buoyancy is more at Bottom surface. Net force is in upward direction hence block move upward \r\n pressure increases at depth p alpha d P = Pressure d = depth Yes, force B_u, It is the downward force exerted by upper water column on block. Weight of object (mg) will also Act in downward direction.
