What will be the force required to exert a pressure of 20000 Pa on an area of 1 cm ?

Sure, let's solve this step by step.

Step 1: Understand the problem We are given the pressure (P) which is 20000 Pa and the area (A) which is 1 cm². We need to find the force (F).

Step 2: Use the formula The formula for pressure is P = F/A. We can rearrange this formula to find the force: F = P * A.

Step 3: Convert the area to the correct units The pressure is given in Pascals (Pa), which is the SI unit. However, the area is given in cm². We need to convert this to m² (the SI unit for area) to match the units. 1 m² = 10,000 cm², so 1 cm² = 0.0001 m².

Step 4: Substitute the values into the formula F = 20000 Pa * 0.0001 m² = 2 N.

So, the force required to exert a pressure of 20000 Pa on an area of 1 cm² is 2 Newtons.
