🧠Numerical Practice: Pressure, Area, and Force
Q1: A force of 20 N is applied over an area of 2 m2. What is the pressure?
Pressure = Force / Area = 20 N / 2 m2 = 10 Pa
Q2: Calculate the force when pressure is 200 Pa and area is 0.5 m2.
Force = Pressure × Area = 200 Pa × 0.5 m2 = 100 N
Q3: A boy exerts a force of 150 N on the floor with his shoes. If the area of contact is 0.1 m2, calculate the pressure.
Pressure = Force / Area = 150 N / 0.1 m2 = 1500 Pa
Q4: A woman wearing high heels applies a force of 500 N on an area of 0.002 m2. Find the pressure.
Pressure = 500 N / 0.002 m2 = 250,000 Pa
Q5: A hydraulic press exerts a force of 1000 N on an area of 0.25 m2. What is the pressure exerted?
Pressure = 1000 N / 0.25 m2 = 4000 Pa
