# Class 11 Physics Fluids

Here, from pascal’s law pressure at height ‘h’ is same for any liquid.

So, here pressure at right column,

Pr = ρ* g*l where ρ= density

Pr= 3gl

Pressure at left column, Pl = ρ*g*l

Pl = 1gl = gl

So, liquid A will rise and liquid at base will also rise to height h, suppose.

So Final pressure in left column,

Pl = 2*g*h + 1*g*(h+l)

Pl = 3gh + gl

Now, Pl = Pr

so, 3gh + gl = 3gl

3gh = 2gl

h = 2l/ 3

So, Liquid A will rise for another 0.66l and liquid of base will take place there.
