Question

Calculate the pressure exerted by cubical block placed over the
surface.
m = 50 kg, side length = 5 cm.​

Answer 1

Answer:

Pressure, P =?

M = 50 kg

F = mass x acceleration

F = 50 x acceleration due to gravity = 50 kg x 9.8 m/s2 = 490 N

side of cube is given = 5 cm = 5 x 10-2 m

Area of the face of cube on which the force is applied is A = (5 x 10-2)2m2 = 25 x 10-4 m2

Pressure = Force/ Area = 490 N/ 25 x 10-4 m2 = 196000 N/m2 = 196000 Pa
