Question

Mass of a brick is 2.5 kg. Find the pressure the brick exerts on the ground if
it is resting on 10cm x 5cm base.
Answer with explanation pls...

Answer 1

Answer:

5000 Pa

Explanation:

m= 2.5 kg

a= 10 cm X 5 cm

 = 0.1 X 0.05

 = 0.005 m^2

f= 2.5 kgf = 25 N

therefore, Pressure= fa

                                = 25/0.005

                                = 5000 Pa

Answer 2

Answer:

5000pa

Explanation:

F=mg

=2.5×10

=25N

A=10cm×5cm

=10÷100×5÷100m

=5/1000

P=F/A

=25/5/1000

=5000pa
