the mass of a brick is 3 kg its dimensions are 10cm * 5cm * 2cm the pressure of brick exerted on the ground if its resting on 10 cm and 5 cm base is
Dear Student,
Mass of brick, m = 3 kg
Weight of brick = mg => 3 × 9.8 (g = 9.8 m/s2)
W = 29.8 N
The brick is resting on a base of dimension 10 cm and 5 cm
Area of base = l × b
Area = 10 × 5
Area = 50 cm2 => 5 × 10-3 m2
Now,
Pressure = Force/Area
P = 29.8/5 × 10-3
P = 29.8 × 103/5
P = 5960 N/m2 or Pascal
Regards
