Worked Solution & Example Answer:(iii) Which diagram shows the direction of the forces from the water on the inside of the tank? (b) Figure 3 shows three containers A, B, and C - Edexcel - GCSE Physics - Question 3 - 2016 - Paper 1
Step 1
Which diagram shows the direction of the forces from the water on the inside of the tank?
Answer
To determine the correct diagram that shows the direction of the forces from the water on the inside of the tank, we need to consider the principle of hydrostatic pressure. The water exerts pressure on the walls of the tank, which acts perpendicular to the surface of the walls. Therefore, the correct diagram would be the one that illustrates the forces acting directly toward the tank's walls from the water, which typically is represented with arrows pointing toward the walls. In this case, the correct answer is diagram B.
Step 2
Figure 3 shows three containers A, B, and C.
Answer
In Figure 3, we can see three containers labeled A, B, and C. Each of these containers holds different liquids:
- Container A has a layer of mineral oil beneath water.
- Container B contains water above a layer of oil.
- Container C has only water.
This arrangement indicates how the density of liquids affects the layering, with the denser liquids, like mineral oil, sitting beneath the less dense liquids, in this case, water.
