Question

If 5000Pa a pressure is exerted on an object with the contact area 0.04m^2. Calculate the mass of an object

Answer 1

• Pressure = 5000 Pa
• Contact Area = 0.04 m^2
• Acceleration due to gravity = 9.8 m/s^2
• Let the force be F.
• We know, Force = Pressure × Contact Area
• Therefore, Force = 5000 Pa × 0.04 m/s^2
• or, Force = 200 N
• We know, force = mass × acceleration
• Therefore, mass = force ÷ acceleration
• or, mass = 200 N ÷ 9.8 m/s^2 = 20.4 Kg

Answer:

20.4 Kg
