Answer 2

The net force acting on each side= 2PRh +Rρg$h^{2}$  −2RT

Step-by-step explanation:

Pressure at a depth x from the surface of the water = ρgx

Hence net force on each surface of ABCD is  ∫(P +ρgx)(2Rdx), where the lower limit is 0 and upper limit is h.

=2P*Rh+Rρg$h^{2}$

However the side attracts the segment due to surface tension acting along AB=T(2R)

So the net force acting on each side= 2PRh +Rρg$h^{2}$  −2RT
