Question

A mass of brick is 250g its dimensions are 10 cm ×5cm×2cm.Find the pressure a broke exerts on the ground, if it rest on i)10cm×5cm
ii)5cm×2cm​

Answer 1

Answer:

In case 1) pressure = 500N/m^2

Explanation:

P =F/ A

F=mg = 250×1/1000×10

=2.5 N

A=10×5 cm^2

=50×1/10000 m^2

P = 2.5/(50×1/10000)

=500 N/m^2
