Question

Pressure exerted by a body changes when the surface of area of contact changes.state 2 example

Answer 1

hey mate I can't specify the examples but I will give it's two use I.e, if surface area is large then pressure will be less, where as if surface area is small then pressure is more for ex if u place a wooden block on the surface of water then it floats, since it has wider surface but if u place stone , then it sinks because it has small surface area, that's all thank u

Answer 2

Two instances of Pressure exerted by a body changes when the surface of area of contact changes are ----

i) It is easier to write with a sharpened edged pencil ( less area) than a blunt one ( greater area)

ii) A sharp knife can easily cut a fruit(less area) while a blunt one cannot(greater area).

∴Pressure is inversely proportional to area.
