Question

4. A cubical block is kept on the floor as it is shown in Figure 11.30. The length
of the block is 50 cm, the breadth is 10 cm and the height is 30 cm. The weight
of the block is 50 N and it is the force that is acting on the floor. Find the
pressure applied on the floor. Also find the pressure applied by the block on
the floor in other two ways.

plz answer correct​

Answer 1

Answer:

Area = 3cm×3cm=9cm2=9×10−4m2  

& Pressure exterted = 5Pa  

Since Pressure = AreaForce  

               Force = Pressure × Area  

               Force = 9×10−4×5N  

                          = 45×10−4N.
