Question

The base of a container measures 15 cm × 20 cm. It is placed on a table top. If the weight of the container is 60 N, what is the pressure exerted by the container on the table top?

Answer 1

Area of the base of container A = 15 cm × 20 cm

`= (15 xx 20)/(100 xx 100)`

= `300/10000 "m"^2`

`= 3/100 " m"^2`

Force  = weight = 60N

Pressure exerted = `"F"/"A"`

P `= 60/(3/100)`

P `= 60 xx 100/3`

P = 20 × 100

P = 2000 Pa
