d. Both A and B

​

Answer 1

Answer:

because it depends on height only in static conditions. force acting at a horizontal level is product of pressure *area which is due to weight above not below (its like u take 3 boxes five kg each and place them in a stack one above other, the lower box just give normal reaction due to middle box and top one, the actual pressure the middle box experience is due to its own weight +upper box weight but if middle box height reduced to approx. zero(negligible mass )now the pressure on middle box is only due to upper box. so same way if we are observing a layer in 2 different shaped containers like square of 4*4 and rectangle of 4*5 at same height filled up to same level. weight above this layer will be

volume*density*g

pressure equals weight/area = 4*4*h*d*g/(4*4) for square

=5*4*h*d*g/(5*4) for rectangle.

so it seems it depend on h only

as for a horizontal level in fluid shape changes area but area got cancelled as above so no effect due to shape in hydrostatic.

hope you got the Answer
