Question

a brick is 20 cm long 10 cm wide and 10cm thick and weights 24n and is laying on the ground find the pressure exerted by the brick on the ground

Answer 1

Answer:

If the brick is kept by it's length.

If the brick is kept by it's length. Then ,

If the brick is kept by it's length. Then ,the base area = 30cm = 0.3m

If the brick is kept by it's length. Then ,the base area = 30cm = 0.3mand force = 24N

Hence, the pressure = 24/0.3 = 80pa.(as pressure = force/ area)Similarly,When it's kept by it's widththen, pressure = 24 / 0.1 = 240paand this would the same pressure when it's kept by it's thickness as both are same..........☺
