____________

Force = 20N

Area = 0.1mm^2

1mm^2=(1/10cm )^2

So....

0.1mm^2 = (1/10×0.1)^2

0.1mm^2 = 1/100×0.01

0.1mm^2 = 10^_4cm^2

1cm^2 = (1/100m)^2

10^_4cm^2= (1/100)^2 ×10^_4

10^_4cm^2 = 10^_8m^2

P =?

P=F/A

P = 20/10^_8

P= 20×10^8Pascal

INSHALLAH it will help U

ish30181551: what step u have written after o.1mm^2=1/100×0.01

ish30181551: plz tell

ish30181551: and also tell me solution of another 3 question I asked

ish30181551: plz help me

Anonymous: 1/100 means 10^_2 and there is another 10^_2 So this becomes equal to 10^_4

ish30181551: why u had putted underscore_

ish30181551: and plz tell me another 3 solutions for the question I asked

ish30181551: plz ... plz.... plz.... help me ...

Anonymous: it is 1/10^2 but in numerator its sign will change it will become 10^_2

ish30181551: ohh ! ok thanku.....☺☺
