Question #8bc67

Answer 1

Let a body of mass `m\ kg` be resting on a horizontal surface. Let the area of contact be `=A\ m^2`.

Force exerted on the surface by the body`=mg\ N`
where `g=9.81\ ms^-2` is acceleration due to gravity.

Pressure is defined as Force per unit area.
`:.` Pressure is given as `P=(mg)/A\ Pascal`
