Question

9. A force of 12 N is acting on a surface of area 4 m². If the force is doubled and the area of the surface is made half of the initial area, what would be the difference in pressure?
10. Imagine you are provided with a plastic container, water and a needle. With the given material, how can you prove that liquid pressure is same at equal depth?​

Answer 1

10. we make 4 holes around the bottle at same height. We can observe that water flows out with equal pressure from all holes. So, we can say that liquids exert equal pressure at the same depth. Hence, This is required answer.
