When the support is acted upon by a force of 20N, the pressure on it is 200Pa. How many times will the pressure change if the support area is halved?
We know the formula p = F / S, in which p is pressure, F is force, S is area. S = F / p. If F = 20 N, and p = 200 pa, then S = 20/200 = 0.1 m ^ 2. If the area is reduced by 2 times, then it will be equal to 0.05 m ^ 2. Then the pressure will be 20 / 0.05 = 400 Pa. 400/200 = 2 – this means the pressure will double.
Answer: Will increase 2 times
