Question

Pressure exerted on a floor when a book of mass 2 kg is kept on floor with the dimension (20 cm — 5 cm) will be: [take g = 10 m/s2]

Answer 1

----------------

SOLUTION

----------------

Mass of book = 2kg

Surface area of book = 20×5

= 100 cm2 = 1 m2

Force = mg = 2×10 =20N

Pressure = force / area

= 20/1

= 20 Pa
