The correct option is B FA=FB;WA>WB
since h is same for both vessels,pressure=ρgh is the same.Nowforce=pressure× base area.since the base area is the same,the force exerted by water on the base is the same for both vessels.thus FA=FB
the liquid exerts pressure, and hence force not only on the base but also on the sides of the vessel. this force is normal to the side of the vessel.for vessel B,this force has no component in the downward direction.but for vessel A,this force has a non-zero component vertically downwards.hence vessel A gives a higher reading than vessel B when they are weighed on the weighing scale.thus WA>WB
