Question

state the factors on which pressure exerted on a rough surface depends​

Answer 1

pressure depend on :-

i)) force applied

ii)) area of surface

Answer 2

The factors upon which pressure depends are as follows :

→ Pressure is directly proportional to the force applied .

→ Pressure is inversely proportional to the area on which the force is applied .

EXPLANATION :

Pressure is the force applied per unit area .

Formula for pressure is given by :

$Pressure=\frac{Force}{Area}$

Hence pressure is directly proportional to force .

P ∝ F

This means that pressure can be increased by increasing the force applied .

This also means that pressure can be decreased by decreasing the force applied .

Pressure is inversely proportional to the area on which force is applied .

P ∝ 1/A

This means that pressure can be increased by decreasing the area .

This also means that pressure can be decreased by increasing the area .
