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?

योग

उत्तर

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
