Isothermal condition is there , and using P1V1=P2V2 , we say that here P1 and P2 r the pressures exerted on the wall by the gas , so why we r not using avg force concept for side walls and why to take h1.rho.g as this is the pressure exerted by the liquid...

Doubt regarding free fall of block in inclined plane...

"Find acceleration (a) of Inclined plane, so that Block (m mass) will free fall",, now wherever I see the answer, it's always "For free fall N = 0, so ma sin theta = mgcos theta"... My doubt is that, to free fall a block, all you need is mg, right? So, why only N = 0, ma should be = 0 also.. even, N should cancel ma.. so that only mg remains.. but if we do N=0 its just Normal force being 0, the horizontal acceleration remains there. I think N = mgcos theta should be answer.. but it isn't...
