# A force of 400N acts on a surface of area 25 square cm. calculate thrust and pressure. calculate the changed pressure if the force is now 600N

SURFACE AREA = 25cm^2 = 25 X 10^-4

THRUST = ?

PRESSURE = ?

THRUST = 400N(THE FORCE ACTING ON AN OBJECT PERPENDICULAR TO THE SURFACE IS CALLED THRUST.)

PRESSURE = THRUST/AREA

P = 400/25 X 10^-4

P = 16 X 10^4 N/M^2

NOW,

IN 2ND CASE WHEN FORCE 600N ACTING ON THE SAME SURFACE THEN THE PRESSURE :

PRESSURE = THRUST/AREA

P = 600/25 X 10^-4

P = 24 X 10^4 N/M^2.

plzzzzzzzzzzz MARK AS THE BEST ANSWER..
