Question

a force of 200N acts on a surface of area 10cm2 calculate thrust and pressure calculate the change pressure if thecarea of constant increases 50cm2

Answer 1

HELLO DEAR,

Thrust = Force
= 200N

Pressure1 = Force/Area1
       Force = 200
   Area1 = ​0.001 m^2

Pressure1 = 200/0.001 = ​200000Pa


Pressure2 = Force/Area2
      Force = 200N
  Area = 0.005m^2
Pressure2 = 200/0.005 = ​40000Pa

I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

thurst is defined as force per unit area
and pressure is also define as force per unit
so both are same in this question
pressure=force/area
1m=100cm
1m2=10000cm2
1cm2=1/10000m2
pressure=200/0.0010=200000N/m2
and thurst = 200000N/m2
area of constant increase to 50cm2=50/10000m2=0.0050m2
now ,
pressure= 200/0.0050=40000N/m2
change in pressure=final pressure - initial pressure
change in pressure = 200000-40000=160000N/m2
i hope you may understand the solution
