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......
