In, the proof /derivation of exess pressure inside air bubble in a liquid
Fp2=Ft+Fp1
Fp2.......> The force due to the pressure from inside the bubble.
Fp1........>The force due to the pressure from out side the bubble.
Ft..........>Force of tension .
'Ft' will be balanced by the other other hemisphere of that bubble . But why it is taken to be balanced by 'Fp2' &
prove /derive Ft=2piRT.

but sir density as we go deep keeps on changing then why the pressure should be calculated keeping density 1,,,, also as we go down the same volume of liquid would weight different and hence different pressure.
So you cannot tell me anything about contacting,.....well okkk
Sir my question which i wanted to address was A rectangular plate of dimensions 6cm*4cm* and thickness 2mm is placed with its largest face on the surface of water. findd the downward force on the plate due to surface tension. surface tension of water is 7*10^-2 N/m

can you please guide me through the means to contact topperlearning, i have been given a no. of shikha ma'am and i lost it, now I am having some queries, which i tried to get solved by dialing no., one which is on the site,but it didn't worked. In last question, i wanted to ask why while calculating change in pressure (3*10^5*980) is calculated keeping density uniform for we know pressure= height of vertical column*density* acceleration due to gravity, why density is assumed to be 1g/cm^3 I am worried i am loosing my net question allowed limit,,,,,,by discussing questions again,, tell me pls what is this limit is or give me the no. of shikha ma'am Would you pls answer my second question in this querry???pls
