Question

These are the numericals in physics of chapter - pressure                                                                                                           Q1)what force will exert a pressure of 50000 pascals on an area of 0.5 meter square ?Q2)find out the area of a body which experiences a pressure of 500 pascals by a force of 100 NQ3)calculate the pressure exerted by a force of 300N(newton) acting on an area of 30cm squareQ4)what will be force required to exert a pressure of 20000 pascal on an area of 1 cm square ?so these are the questions to be answered ... referring to the answers you can give the solutions :) plzzzz help me out with this its urgent . it is to be submitted by tomorrow itself!!!Answers for the above questions are :(Q1) 25000N (Q2) 0.2 meter square (Q3) 10 N cm-square = 100,000 pascal (Q4) 2 N

Answer 1

formula for all 4 questions are same.......i.e, pressure(P)=force(F)/area(A)

Q1) given:-pressure=50,000pascal
                  area=0.5m2
              
force=PxA
         =50,000x5/10
force=25000N

Q2)given:-pressure=500pascal
                 force=100N

pressure=force/area
area=force/pressure
area=100/500
area=0.2m2

Q3)given:-area=30cm2 =30/100m2
                 force=300N
pressure=force/area
pressure=300/30/100
pressure=300x100/30
pressure=30000/30
pressure=1000pascals

Q4)given:-pressure=20,000pascals
                 area=1cm2=1/100m2
pressure=force/area
force=pressure x area
force=20,000 x 1/100
force=200N

hope it will help you..............
