Question

A force of 100N acts on a surface area of 25sqcm.Calculate thrust and pressure .Calculate the changed pressure if the force is now reduced to 25N

Answer 1

thrust= 100N
area= 25sq.cm=0.25sq.m
pressure= thrust/area
= 100/0.25
=400 pascals


if the force is reduced to 25N then;
pressure=25/0.25
=100 pascals .

hope it helps.......

Answer 2

Force=100N(newtons)
Area=25 cm sq (0.25 in m)
Pressure=Force/Area
=100/0.25
=400 pa(pascals)

Force reduced to 25N
Then,
Pressure=25/0.25
=100pa

Hope it helped you..........
