  • The water exerts the same pressure on the base of each vessel.
  • The water exerts the greatest pressure on the base of vessel S.
  • The water exerts the greatest pressure on the base of vessel P.
  • The water exerts the same force on the base of each vessel.
When you increase your depth under water, the water pressure on your body

  • The design of this structure is stronger.
  • Water pressure increases with depth.
  • The cost of construction is lower.
  • Water pressure acts uniformly in all directions.
