Question

) Calculate the pressure exerted by a book of size 10cm x 20 cm if the mass of the book is 200 g in SI unit.​

Answer 1

Answer:

We know that:

pressure = \frac{force}{area}

We know that:

f = ma

Therefore Force =0.1kg*9.81m/s^2

=0.981N

Therefore area=10cm*20cm

=0.1m*0.2m

=0.02m^2

Therefore Pressure=0.981N/0.02m^2

=981/20

=49.05N/m^2

=49.05Pascals
