Subjective Type

Name two factors on which the pressure on a surface depends.

Solution

FACTORS AFFECTING THE PRESSURE.
(i) The surface are $$ (A) $$ on which thrust acts. More area , lesser is pressure.
(ii) The magnitude of thrust $$ (F) $$ acting on the surface
$$ \because P = \frac {Thrust}{Area } = \frac {F}{A} $$ More thrust , more is pressure.
