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?
Solution
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
