Answer –
- Mass = 50 kg
- Length = 5 cm = 0.05 m
We need to find the pressure exerted by cubical block.
Finding the total surface area of the base of the cube:-
Formula : side²
Hence, Area = 0.05²
Area = 0.0025 m²
Formula for Pressure : Force/Area
We also know that, Force = mass*gravitational force
Pressure = 50*10/0.0025
Pressure = 500/0.0025
Pressure = 5000000/25
Pressure = 1000000/5
Pressure = 200,000
Pressure = 200,000 Pa
