A block of size 20m x 10 mx 5 m exerts a force of 30N. Calculate the

maximum & minimum pressure exerted by the block on ground? hello yeah tell me the answer of this question

We know that force applied per unit area is called pressure.

Pressure = Force / Area

When force is constant than pressure is inversely proportional to area.

1 - Calculating the area of three face:

A1 = 20m x 10 m = 200 Square meter

A2 = 10 mx 5 m = 50 Square meter

A3 = 20m x 5 m = 100 Square meter

Therefore A1 is maximum and A2 is minimum.

2 - Calculate pressure:

P = F / A1 = 30 / 200 = 0.15 Nm⁻² (minimum pressure)

P = F / A2 = 30 / 50 = 0.6 Nm⁻² (maximum pressure)

Hence greater the area less will be the pressure and vice versa.
