Question

A force of 1200N acts on the surface of area 10 cm2normally. What would be the pressure on the surface?

Answer 1

Answer:

Pressure = F/a (Force per unit area)

F = 1200n

a = 10cm² = 10/100 × 100 = 0.001

P = Fa 

→1200 × 0.001

→1.2 n/m² = 1.2pa        (pa means pascals)

Answer 2

Answer:

Given,

F=1200N

A=10cm²=0.001m²

We know that ,

P= F/A

P=1200/0.001

P=1200000 pa or N/m²
